For the record, the Librem 5 does indeed support many of those apps via Anbox.
We also need to stop talking about individual purchasing decisions as if they represent the broader market. The point is not that there are zero competitors in a monopolised market. It’s that those competitors suffer at the will of the monopoly and cannot bring viable competing products to market. Hence all the competitors outside of the big two in the mobile space having effectively zero market share combined.
Far from forcing people to develop something anti-trust is design to increase competition by opening up the market. Offering more people the opportunity to build the innovative things they want and consumers the ability to choose. As we saw with the results in this happening to MS it works reasonably well.
Like what the hell am I supposed to do on a purism libre that has 100x less apps of 1/10th the quality as iOS? It currently does not support signal, banking apps, maps, Spotify, slack, Feedly, pocket and millions more. Yes, a dev could potentially spend 100s of hours making shitty homegrown alternatives for every little app - this is a VERY long stretch. And even then 99% of people are not devs and will never ever ever do that. It’s like saying a horse is a viable alternative to a car. It’s not even in the same damn universe yet.
