Alex Russel, a developer, team lead and developer advocate for Google for 13 years from 2008 to 2021. He's one of the primary people responsible for the web components mess.
He's quite well known in hte web/web-adjacent world. During his work at Google he would:
- go out of his way to blame and gaslight Apple for everything
- defend and any and all Chrome-only non-standards that Chrome was (and still is) churning out at ever-accelerating rate, completely ignoring any and all standards processes, or other browser vendors' input
- be completely silent on "how Google killed mobile web" and only blaming Apple
Once he went to work for Microsoft he started bashing Google, too.
The amount of grains of salt tyou need to take to read anything he writes that is not strictly technnical would cause world-wide salt deficit for any forseeable future.
Digging in, it seems like they worked on Chrome for several years before moving over to Edge. That would give them at least some technical insight into what happened at Google, if not the reasons behind those decisions.
Even so, it still feels like a lot more speculation than actual facts.
But that's me.
