I think a long time ago a vicious cycle began in the advertising space where predatory ads had more incentive to pay for ad space, so sensible people start to perceive ads in general as predatory. Now no sensible advertiser that’s trying to promote a legitimate product for legitimate reasons will do so by buying ad space, thus reinforcing the increasingly accurate perception that all ads are predatory.
Which is exactly the position that the Rust for Linux devs have understood and accepted for themselves, and yet they still get yelled at (literally, in public, on recordings) by C Linux devs for existing.
Oh and they get snidely told that introducing the Rust language must be a mistake because suggestions to introduce other languages to the kernel turned out to be mistakes and obviously Rust is the same as all those other languages according to C developers who, by their own admission, have never used or learned anything about Rust beyond a superficial glance at some of its syntax (again this was recorded from a public event).
