You can always run your own company-internal or limited-to-your-home CA and add it as custom root CA to every browser in that domain. These maximum certificate validity rules IIRC don't affect custom root CAs you added.

I agree with you that the web is being commercialized, but limiting certificate lifetimes isn't the problem. It's rather stuff like the .org domain sale, google amp, Chrome killing the file:// protocol (after all, html files don't have ads inside them, can't be indexed and they don't make any money for Google), FLOSS projects adopting discord, etc.
