But it is not secure! That's the entire point.
Never mind "not secure against a well funded government agency", it's not secure against other attackers.
There are lots of usable chat apps that do not give you the illusion of security.

You seem to be mistaken about why they do this. It's nothing to do with pushing their app or their approach. They'd welcome good well-formed apps to compete with them. But when they see an app that claims to be secure they have an ethical duty to let people know if it is obviously not secure.
Most people are not bashing just for the sake of bashing. Some people need good cryptography software to avoid imprisonment, or torture, or state-killing. This isn't about stopping someone's teen-angsty poetry from being discovered by a sibling, it's about protecting political dissidents from an oppressive regime. In that context pointing out that a software is broken is not mindless bashing, it is a crucial part of the cryptography process.
(I'll accept that a few people are missing the mark with their criticisms.)
Pointing out flawed crypto software is part of a long tradition going back many years. It's part of the culture. Most cryptographer will start by analysing other software and finding flaws before implementing their own software.
