Who do they consider their target audience? Who needs a Mozilla metaverse, a Mozilla social Mastodon instance, a landing page generator?
Why can't they invest into something with a vision, something complex, a long-term hard tech? I don't know, re-write FF in Rust or something.
By now they could have had it on large market of cheap phones with an app store to give some revenue. The phones with USB C could be a basic PC, like they envisioned in design concepts back in 2010.
Add slick, basic desktop to growing market of raspberry pi like devices... they'd have integrated their browser everywhere.
The chance to offer a phone that is also a PC is something no companies want to offer. They can't risk cannibalizing their existing products.
Mozilla should have done it.
Anyone curious and don't know my reference, search for 'mozilla seabird concept pico projector'
