The reason you gave here for Brave not choosing Gecko (or WebKit) is interesting – but given Microsoft's deep pockets and tech know-how those reasons don't apply to them.
I think this is a strategic blunder on Microsoft's part and I say this as a Linux user. :)
Microsoft has now warmly embraced Linux – and I think they could have chosen this time to warmly embrace Mozilla. Oh well.
I hear what you're saying – but! – a tech giant has to play the long game. The Web is an open (for now) platform and Microsoft, like Apple, like Google, need to have their own web client/server implementation. Makes no sense to be beholden to Google imho.
I'm stunned at how little desktop browser share Edge has (4.6%): https://gs.statcounter.com/browser-market-share/desktop/worl... – however, changing browser engine is not going to change that, is it? I suppose, if Google and Microsoft end up equally and democratically sharing Chromium development then all's well.
Given the recent layoffs at Mozilla it's a pity (in hindsight – for the benefit of the open web) Microsoft didn't back them :(
Anyhow, thanks for the response.
So we switched to chromium/Blink in late 2015. Much later, when I visited Apple in early 2017, a devrel friend asked why we couldn't use WebKit. A WebKit founder in the meeting agreed with me that there was no way for Brave to do so on Windows w/o running out of capital. DRM again was an issue too, without WideVine. Don’t blame startup for not carrying a full engine — that needs deep pockets. While MS does have deep enough pockets, it is starting by using chromium/Blink and slow-forking.
