Lets see; a phone os no one used, and ad on installed without user permision as a tie-for a TV show, browser integration with a thirdparty bookmarking service that should have been an optional addon, a VPN, an abborted browser based video confercing service based on open standards that they killed for non obvious reasons, a bunch of social justice initiatives, an email masking/forwarding service killing their addon APIs in favor of googles more limited api.
To be fair to the vpn product, at least they did it through a partnership with mullvad, one of the least-terrible (not even in the same ballpark as the likes of nordvpn, etc) commercial vpn service providers in existence.
