But what if most people don't actually care about these freedoms? What if we're only a small minority? Should we force our views on others through laws and regulations or should we, as free individuals, choose not to use these applications and let others make their own free choices?
While I agree a lot of open source messenger services have terrible UX, I don't think "the masses" care about it that much. What matters is what everyone else is using. People are using Snapchat or Instagram Messenger and I haven't seen a single person who likes the UX of those services - they just use it and put up with hatred for it because that's what all their friends use.
I think this is purely first mover advantage. We get stuck with bad products simply because those were the first products on the market. It is difficult to change them once everyone uses them. The same applies to the adoption of IT on the banking industry. Now we are stuck with COBOL and systems that are hard to migrate without damaging the economy.
