Honestly mentioning Enchrochat together with other mainstream message clients is kind of misleading. The Enchrochat message client was also E2EE. However Enchrochat was also a company that sold their own mobile phones with a prorietary OS on it together with own sim cards and only those phones were able to connect to each other. And law enforcment had enough evidence that they sold those hardware in shady untracable ways similar to drugs. At that point there was no western government that didn’t want to help seizing their infrastructure and taking over their update services for example.
The bigger problem however for the general public is that certain politicians want to break encryption all together by forcing companies to implement backdoors on client side. This has been an ongoing discussion for 2 years in EU parliament and it has to stop: https://www.eff.org/deeplinks/2024/06/now-eu-council-should-finally-understand-no-one-wants-chat-control
