app store "monopoly"? No one's forcing you to use the Apple ecosystem. it's called Android.
There is side-loading, but there's a lot of friction there that I wouldn't expect normal users to withstand.
There are countries with 0% iOS market share, half of zero is still zero.
A single big company doing this just to cut down on some fees just reeks of greed.
The world is unfair, no one is expected to do charity for developers.
We are not a special snowflake job that isn't expected to give others the necessary payments to keep the whole chain working.
