Use Firefox/Fennec which allow you to install a variety of the add-ons you can install on the desktop version such as UBO, Stylus, ViolentMonkey, Bitwarden, SponsorBlock, etc... or install Brave which comes with adblock by default. As for iPhone, you can install Brave which has adblock, I don't think Firefox has add-ons in that version though, not sure.
I don’t think you can write off Apple or Microsoft just because Thiel made some investment in them.
Being the VC to a company’s round B, C, and D (adding up to maybe 40% ownership/control) is VERY different from simply throwing some money at a trillion dollar company to see some returns.
