Small fraction of users but a huge fraction of the market share (and revenue generation share). Being that the DMA was specifically targeting these two things it seems quite at odds with "A free app like Chrome must pay us millions if it wants to distribute itself instead of using the legacy terms deemed illegal". If they didn't allow legacy terms it'd have a bit more of a leg to stand for opening the markets, same as if it didn't apply to apps distributed via third party, but the way it is now seems a contentious combination.
