I really do not see any logical basis that makes you separate privacy friendliness from User Friendliness. If a platform wishes to be user friendly, privacy is also one of the fundamental rights of a user the platform needs to take care of for it to be considered friendly to a user.

The fact that a lot of people, not ‘everybody’, are comfortable with Instagram has no strong points to consolidate your own position. It only describes how good the horrible marketting of Giant Tech Corporations is at entrapping millions of people into using it, generating life long addictions and the eventual wastage of time on degenerate culture. While the Corporations collect all that data available to them to further their own Capitalist interests.

Privacy does come at a cost and compromise. A slightly less funkier UI for a far more secure platform, for essentially 0 cost is a lot one could ask for, especially when you are comparing a Libre project made by a small organization to a proprietary project made by a Multi Billionaire MNC.

I will not be apologetic in saying that you are the child here who is tailing the mass of consumers without proper analysis.
