I must say I have to disagree, I'd elaborate on why I think it might be a useful move, but that'd be digressing even further.
And more importantly, engaging in lengthy discussions in threads like this are proving to be way too much of a time-sink, very briefly:

We don't have the figures, but I reckon there's a good chance that some of the newest Android ODM's are already selling much better than the Jolla*, or will very soon.
I think there's way more people out there who want "another boring Android" than a device with Sailfish on it, & it has very little to do with Android being a vastly better OS.

That isn't stopping many new players, some which I'm happy to wager will be around in x years, & biting large chunks out of the market-share of today's supposed "immovable titans".

I didn't say that, anyone who got that impression from what I wrote may have misunderstood my point...


*or as well at the very least, but with better margins because total overheads are less
