You are doing some pretty serious mental gymnastics to find issues with Framework. Most parts are open sourced and easy to get ahold of. The parts availability and ease of replacement are lightyears beyond what most companies do. The replaceable ports are not restricted to buying theirs, many people have dedigned and built their own cheap ports and open sourced them. Try buying a laptop from any other manufacturer, and attempt to replace anything. You will be in a world of struggle. You can almost build an entire Framework directly from their marketplace. Oh, ans having stakes in a company does not mean ownership.
My problem with Loops is the same problem I have with Pixelfed. They are both only maintained by the same one guy. No team, no support besides him. Its only a matter of time before they are dead in the water due to burnout or shifting interest.
