You haven’t addressed the issue I’ve raised.

I am and will continue to be concerned with businesses because I’m a human being who needs to eat and has a life outside my home.
I am telling you that most businesses only use Instagram in place of any other means of notifications.
It’s currently not possible to keep up with events without having an Instagram account. I already miss out on most events because the instagram algorithm usually shows me posts that are days past the event and I’m not on there for more than an hour in a whole month.

Your solution, to abstain from life, is not feasible. Maybe it is for you but for most people it’s not.

You are also missing the point of the matter where these businesses are going to continue to use a platform that is now explicitly censoring information and seemingly pushing fascist agendas. If you were a business and wanted to maintain a relationship with your customers, what option do you have? As I’ve said, the tools to use social media to run a business have been refined for years. There’s nothing close to comparable either in the fediverse, with websites, newsletters, rss feeds, calendars, etc.
