How would this be different than the Author's Guild negotiating ebook rates with libraries/Amazon? It seems like lots of industries have lobbying groups that represent multiple companies -- or is there an extra nuance here I'm missing?
If uBlock Origin stopped supporting Chrome, AdBlock would fill that void. If Honey has problems, an executive from Ebay calls an executive from Google and it's fixed instantly, so there's no incentive for them to participate. In fact, anyone making a decent amount of money isn't going to want to change the system.
Better brand recognition - more people switched off IE to Chrome than from FF to chrome (hence why I’m not putting the terrible performance and reliability issues that FF used to have like crash and lose all tabs as a factor but it took a decade for FF to sort their shit together and by then it was too late).
Better integration with Google services right when a Google account became quite important.
Being the default browser for the Android eco system.
So I don’t know who would exactly leave Chrome because of extensions but I have a feeling that even you wouldn’t.
If this were true, wouldn't that make it even less likely that an Extension Guild would fall foul of antitrust regulation?
