And how is this helpful? Is this a solution? What if the app-in-question was a different one? Not using Instagram at that would be very helpful, indeed...
Of course it's a solution. The developer has a right to comply with the law in whichever way they see to best fit their needs as a business. If you don't like it then don't use the app, nobody is forcing you to and you don't have a right to dictate to others how to run their business.
The key point here being "comply with". "Let me track you or you can't use this", confusing or coercive "consent" dialogs etc. don't comply.
