As somebody whose wife just downloaded opera onto the family computer I am horrified.
She's been complaining that the internet is slow and has blamed it on protonvon, so has resorted to turning the vpn off when using the internet or discord.
I remember after Twin Peaks season 3 came out, showtime was stating left and right how profitable the show was, and then accusations started flying that the show was so profitable because showtime was taking over the browser while people were watching and mining bitcoin in the background without telling people they were doing so.
I trust Opera about a thousand times less just because I had never hears of them until a week or two ago.
