Competition and organizing individuals is also a real thing, arguably there are ~74 million Americans who voted for Trump - which is arguably a large enough market size to cater a product to, which is exactly what Parler has done under the guise of a "free speech" app - which it's not:

'Stop calling it a “free speech app”. Historically Parler is harsher on dissenting political views than any of their competitors. Just, ya know, against the “other side”.' - https://www.reddit.com/r/technews/comments/kts86k/comment/gi...

There's so much learned helplessness, victim mindset- and a sign of an unhealthy, non-critical thinking, more unreasonable population.

Even if Trump voters all supported the riots - the majority don't - they aren't going to buy a new mobile phone just so as to install Parler on it.
