Completely agree. I understood WebKit to be a different browse engine than chromium or Firefox.
While chromium and Firefox have wider platform options, there’s “kind of” a 3rd runner even though locked to apple.
I agree Linux and open source is king.
Don’t worry. If you upgrade to a premium plan, you won’t be eligible to get any discounts anymore. Nothing offered to existing customers even if purchasing annually.
