I trust my data with my ISP farrrrrr more than I do meta, and also I’m very unconvinced my ISP has access to anything at all here.

You’ll still have Instagram! Don’t think of it as handing over your private communication to your phone carrier, think of it as “also having that choice”. It ps a step forward to have more choices.

I’m somewhat hopeful, since mobile carriers are somewhat regulated. They can be forced to care. Meanwhile, something like Instagram is a private company with noe oversight, who can choose to do almost anything they think will bring in more money
