Its sad that we are in a situation where a company can dictate what we can install on our computers/smartphones. I know we can sideload apps on android, but the majority of users doesn't care about this and just give away its freedom to really own the device in exchange for the easiest way to operate it. And every day we walk towards lesser control of our property and more dependency of those companies.
Another problem is that developers can, without notice, be locked out of their incomes for whatever reason without ways to properly appeal. Those who can, we should consider supporting the developer Xavier Guillemane on Patreon, at least until this situation gets resolved. The amount of work he put on the app, its probably his main source of income and I wouldn't like if he need to abandon the app development due to this. The lowest tier is just $1.
