My fuck-you-right-back response is I don't sign up and give up using the app. I had an instagram account and deleted it years ago. I don't want a new one. Sadly instagram is sign up only, so good luck to them and good bye.
The above is obviously my words and not from a direct quote, but I am using that strategy - for me Facebook is great for finding things that happens around here and so I visit it for a few minutes a couple times a week. Sadly most of my friends are on messenger, so I have that installed on my phone.
I haven't seen a need for Instagram, so I don't use it. I used to use it as a strictly photo posting place, but I stopped that hobby.
