Have you reported it to them? I have nothing but praise for the EC on the way they have handled the few complaints I have registered regarding such things.
I wholeheartedly disagree. Just because you think they meet the criteria doesn't make it true. What are the metrics on chrome web store usage that make you believe it meets the criteria? The figures I can see mentioned online would reflect only a minority of chrome users even using plugins.
I dont disagree with your thoughts on the chrome web store being unfair and anticompetitive, but the DMA is VERY specific in its reach. You can still approach them with complaints unrelated to the DMA of course - but if your complaint was "they should be a gatekeeper", then you will likely be out of luck.
Chrome is a gatekeeper and for that gatekeeper they have another gatekeeping service where they gatekeep what add-ons are allowed and which are removed (as happened with AdNauseam). There are no seperate distribution channels for users. If this is not a gatekeeper, then the App Store can't also be a gatekeeper.
I thought support from Google was "talk to the hand"; all the time I see posts where people got no satisfaction from Google make it to the HN front page.
I was referring to reporting to the European Commission - an example of the “antitrust enforcers” you were looking for. They need to know of issues to investigate them. The more reports they get the more likely it will be raised for investigation quickly.
