DeGoogled Android user?

Google's next-generation reCAPTCHA, presented to desktop users, prompts you to scan a QR code.

The catch? Google Play Services have to be enabled in order for it to work on these devices.

Let's dig in to what has changed, and possible solutions...

1/7
This should be a familiar sight to anyone who has used Google search, or just encountered a website with Google's reCAPTCHA.

Resources are walled off and a 'challenge' is issued.

If you solve the puzzle (identify cars, bicycles, stairs, whatever) you can carry on.

2/7 Image
Google's new reCAPTCHA, however, presents the user with a QR code, requiring they scan it in order to advance to wherever they're going.

On iOS devices, even old versions, this is a simple process.

On Android devices, it will not work without Play Services v25.41.30+.

The EU just exposed Meta's age verification system.

They've just found Meta guilty of violating the Digital Services Act for failing to keep children under 13 OFF Instagram and Facebook.

What they discovered is shocking...

1/9 🧵
Rules & enforcement are a joke.

Terms say: "You must be 13+" but if you want to report a child under 13 on the platform **IT TAKES 7 CLICKS** to access the form.

The form also doesn't auto-fill.

And when you do manage to report a kid? Often nothing happens...

2/9
The numbers don't lie; Meta claims very few kids under 13 use their platforms.

Meanwhile, evidence from across the EU shows that 10-12% of children under 13 are already on Instagram and/or Facebook.

Meta's own assessment is both incomplete and arbitrary.

The Proton ecosystem has grown significantly, with private AI, a 2FA app, encrypted spreadsheets, video calling, and appointment scheduling all joining the ranks recently.

Now we're sharing our spring/summer 2026 roadmaps.

Here's what's coming...

🧵 1/13
Proton Mail: Your inbox is getting more organized.

A new category view automatically sorts emails by type, so attachments and key messages are easier to find.

Focus on what matters, cutting through the noise. Turn them off or on at any time.

2/13
Multiple inbox management is also coming.

You'll be able to send and receive from your existing Gmail address directly inside Proton Mail.

Retain your old address while you settle into your Proton Mail account. Support for more email providers is also planned.

The era of end-to-end encrypted DMs on Instagram is coming to a close, luckily we’ve got a ready-made list of WhatsApp alternatives (which are relevant here too) if you’re looking to shift conversations elsewhere.

(and to be clear, you should…)

1/10 Image
Let’s start with the gold standard:

Signal

🔐 End-to-end encrypted by default
🧾 Collects almost no metadata
🔍 Open-source + independently audited
📞 Calls, groups, disappearing messages

Downside: requires a phone number

2/10
Telegram

📱 Huge user base
⚙️ Feature-rich (channels, bots, multi-device sync)
⚠️ NOT encrypted by default
🕵️ Collects a lot of metadata

Note that only “secret chats” are actually E2EE, and most people never use them

Hanging out in spicy Discord servers? Well this one’s for you! 🌶️

But even if you aren’t, read on...

Discord is expanding its age verification to all 200+ million (or so) users worldwide.

Until verified, all users will be "teen-by-default", affecting what they can see.

1/6
Unless verified as an adult:

- No access to age-restricted channels, servers, & commands
- Mature content will be blurred
- You won't be able to receive DMs from unknowns
- Friend requests from unknowns will come with a warning
- No speaking on Stage (streaming) channels

2/6
Discord are keen to point that, in most cases, its new inference model with analyze data and decide if you're 18 or over with available data.

Private messages will not be analyzed for this.

If the inference model can't decide you're an adult, it'll ask you to verify...

If like many across the world you'll soon be off and looking for something to do, here’s your annual privacy & security tune-up.

Audit your browser extensions

Why?

People add extensions to their browsers for many different reasons.

They will often have wide-ranging permissions, meaning they could access and track your online activity.

Not useful? bin it!

Even if it is, proceed with caution.

2/15
Enable 2FA for anything that matters

Why?

Authenticating with 1 factor, like a password, leaves you vulnerable.

Why would you just use one key to get into your house when you can have the security of two? Especially when that 2nd can be hard-to-fake like biometrics.
