Thank you. Yes, they are also developing their own web engine, which is a very complicated piece of software because of the current sad state of the web. But it doesn’t excuse any of the things I mentioned, and web engine development still doesn’t suckle up that much money as we can see from their current revenue and other efforts to make an independent web engine such as Ladybird.
I agree with you on your last paragraph, but there are some things I’m bothered with. Mozilla is (or was) a company that focused on one thing, their web browser. Apple and Google are (and were) different, in that they have a vast range of products to maintain. And Gecko is most definitely inferior to Blink in terms of speed, although I’m not familiar with any of their “modernity”.
