It will not be if chat control passes, and I am not sure it was true most of the time before (there was no significant change between Brexit and the Online Safety Act)
There were similar problems in areas other than privacy and encryption, or indeed technology.
Key disclosure was law at least a decade before Brexit, so was compatible with EU law, and the other change (the chat control like one) was in the Online Safety Act (and has not been enforced so far because its not technically feasible), so that does not contradict my claim (if that was your intention).
