For me it's > Mozilla develops their own browser engine This is key. Without Mozilla we are aproaching monopoly as Safari aproaches gradually Internet Explorer.
A ludicrous and non-serious statement. Safari leads in several areas, and both it and Firefox push back against Google’s self-serving and privacy-threatening “features” it wants people to think are web standards.
This is the first time I've ever heard someone say this. The overwelming sentiment is that safari is leagues behind, lacks features, lacks performance is has the worst standards support of all common browsers.
What areas are you referring to?
All we ever did at my jobs, when people complained "it doesn't work on safari" is put up a banner for safari users pointing them to either the app-store for our app, or to the fact their browser is not supported.
I've only ever gotten complaints from safari users that stuff was broken (It wasn't, their browser just did stuff wrong/differently/not-yet)
