Clinical echo bubbles
Letting advertisers dictate what can be posted and what can't be posted on social media platforms can only harm free speech imo.
Reddit has lost a lot of users simply because of huge over moderating and deletion of perfectly normal posts, that one person might have reported because they are a snowflake and instead of a mod looking at the post it seems auto-deleted from a report now.
Normies forever complaining about every post on every platform because they have nothing better to do is creating sterile echo bubbles where no one wants to share an opposing opinion because of downvotes, the chance of account banning due to spurious reports etc.
At least we always have IRC to fall back on to for free speech and opinion sharing because most normies can't figure that one out and even if they could, there is no one to complain too.
