It's not like you have a right to appear in Google's search results... I'll rag on Google's poor support as much as the next guy, but only when it's warranted. ProtonMail and anyone else that gets delisted / what-have-you is not Google's client and shouldn't expect first-class support for things like this.
It is not about the right to appear in Google's search results. It is about abusing market dominance to put competing businesses at disadvantage. There are also other running/solved cases/investigations against Google. http://ec.europa.eu/competition/elojade/isef/case_details.cf... http://ec.europa.eu/competition/elojade/isef/index.cfm?fusea...
Asking Google to be responsive to any website demanding special treatment for higher search rankings is unreasonable. Best practices are published and tools are available. It's hard to see monopolistic abuse there.
The only difference is that Gmail (and other Google products) are listed when you, shockingly, go to google.com. Are you saying Google can't mention Google products on google.com? Do you think gmail is somehow not as popular as it is and wouldn't rate the #1 spot for searches for email?
