I've recently rediscovered RSS and I'm in love with it. I just wish Meta wasn't a piece of fuck and let you add Facebook pages and Instagram accounts. there are some workarounds for the latter, but they're really finicky.
That was just for the growth and acquisition phase, using the network effect to capture consumers and businesses, get them addicted and dependent on the product, and then build a wall around them to lock them into your platform.
It's a classic bait and switch, and if we didn't live in corporate dictatorships masquerading as "democracy" it'd be illegal.
Not an RSS solution, but in IG if you tap the "Instagram" logo at the top/right, a menu will pop up. You can select "following" to (mostly) see the accounts you're following (and in reverse chronological order.)
With bibliogram you can follow instagram pages in rss
good luck finding an instance that works.
Facebook pages used to work with rss bridge
I'm well aware of the RSS Bridge and I use several of them hosted on the main instance, but how does "used to work" help? Facebook used to actually provide RSS feeds for their pages and they used to work, too.
You have to selfhost bibliogram, working for me, I usually get rate limited but get all updates once or twice a week.
There is a facebook bridge in rss bridge, for a long time it worked, I don't follow its development nowadays, maybe someone with some php knowledge can resurrect it.
