I don't know anything about the article, but I know Twitter suspended my account immediately after confirming my email and following 1 person. I appealed and they restored it, I logged in and they immediately suspended my account again with no explanation. I don't think it's a conspiracy, just that their automated bots can be trolls

There's a substantial difference between a normal suspension that is "routine" and can get lifted automatically and quickly, vs. being told you're suspended permanently, can't appeal, and isn't allowed to try to register new accounts.
