The terrible idea is only having an algorithmic feed. If you always offer the user the option to not use it and instead have a feed they can control, then it’s a non issue
As soon as the site is owned by a public company, it's over. They are legally required to have an algorithm only feed, as this gives the best engagement, regardless of how much the userbase might hate it.
Algorithmic feeds generate more user engagement, that is what they are for. That's why platforms built around following updates from people that you like can't help themselves but implement them.
how many platforms need to be ruined by an algorithmic feed before people understand that its a terrible idea?
