as explained before, this isn’t an immediate “you on /e/OS” problem, your apps will continue to run.
It’s a developer problem not being able to reach the biggest possible Android audience unhindered and Google Android being no longer a friendly platform for that cohort.
The F-Droid top post says “it will end the project … as we know [it] today” - it can remain a source for customrom users with its full catalog - but it will shrink the available catalog for Google Android users, putting off developers, leading to less newly developed FOSS Apps on Android and some existing being possibly abandoned.
That is what you can consider a “you problem” longterm, the platform getting less developer friendly.
