This is just getting disingenuous you'll have huge posts claiming that you don't need gapps and that f-droid works just perfectly, the vast majority of Android phones are sold without gapps or the google store that is Africa, China, India and parts of Latin America, somehow all of these including arguably the 2 largest single markets get along just fine without it.
Again, not a valid rebuttal. Just because someone doesn't have to use your product (and in this case, I would flat out disagree with your statement) does not mean you get to gouge them on the terms.
There are plenty of alternatives, the largest markets don't use Google, you can't cry that this is anti-competitive when it's clearly not the case since there is plenty of competition.
Google invested billions in Android it can do whatever it likes with it, you don't like it? don't use it, the alternative is for Google to either charge a feed to use Android which would be perfectly fine or to close it off to OEMs completely which again would be completely fine in this context and it would also avert the fine in both cases.
All this fine would do is A) force google to find ways to not pay it and they would likely not pay a single euro-cent in the long run, B) close the Android ecosystem even further down to the point where no other alternatives would be even possible.
If Google was not licensing it out, then sure, they could do whatever they wanted. But they are, and as such, they are not allowed to add anti-competitive terms to their contract. If they don't like it, they don't have to sell their services in jurisdictions with functioning regulators.
