TLDR: not worth reading the article, it's just a long list of third party apps that are no longer free anymore, totally ignoring matters such as their usage stats and more importantly the content itself that is now flat-out missing from Reddit. Go to any old thread and you'll see the "this content has been removed by" (whichever of the automated software to remove posts was used in that case) messages.
Honestly it reads like a shill to promote Reddit as in "hey, all that fuss was for nothing - you should totally come back now". It got fairly obvious even at the start when it said that the protests lasts for "weeks" - not the more truthful "months", not "permanent changes", but the minimum amount they could halfway reasonably get away with stating.
I am biased, and this article is far more so, and less forgivably so bc mine is a personal opinion while this is touted as "news".
