I’d put it slightly differently - an example being @bernardjenkin on #r4today just now. It’s a failure to front up honestly to the trade dilemma and the Irish trilemma.
The trade dilemma is the choice between (1) frictionless trade - but also eg data transfers, continued EHIC cards, to select at random 2 advantages of EU membership Brexiters promised we’d keep - and (2) being free of EU/EEA rules/enforcement. You can’t have both.
Jenkin was honest about the choice but rather less forthcoming about the huge short run consequences of choice (2): disrupted complex supply chains/car production moving/food exports disrupted/no more benefits such as EHIC.
Since voters were promised those wouldn’t happen, (2) the language of betrayal might also fairly be used about choice (2) as well as choice (1).
As for the Irish trilemma, Jenkin had no answer (apart from an inaccurate reference to an alleged pre-Varadkar Irish position). But the trilemma remains. You have to choose one of (1) hard Irish border (2) hard NI/GB border (3) staying in CU (or NCP at least) + SM for goods./end
