but to gain good market share WP needs more OEMs.
I'm not convinced that is true. I'd appreciate an explanation as to why people assume more OEMs = more WP sales.
More marketing dollars?
No... OEMs size their marketing budgets as a fraction of expected sales profits. With the very low profits OEMs make selling WP devices, most have so far looked to MS to fund their marketing campaigns, or even made that a prerequisite to even agree to release a WP device.
More hardware choices?
Doubtful... I have a hard time believing that a notable number of consumers would have switched away from Android or iOS, if only WP would have shipped on devices that looked like the iPhone or the HTC One, which are often sited as some of the best hardware designs currently available.
More recognizable brand names?
The only two brands that matter are Samsung and Apple. Since Apple will never release a WP device, that leaves only Samsung, who is already a WP OEM. Anyone secretly hoping for the Samsung brand to swoop in and save WP seriously needs to share a bit more of whatever it is they are smoking.
So what other reason is there?
Do people suspect that many consumers walk into their local electronics shop, with no clue of what they are looking for, then arbitrarily grasp at one of the devices on display and hope they made a good choice? If those types of consumers represent a notable amount of market share, then flooding the market is probably a viable strategy. I'm just sceptical that is the case.
Seriously, even if three dozen OEMs produced 8 WP models each, I don't see it making a difference. Most stores would simply refuse to stock the devices. If the product you have isn't something a lot of people want, then it doesn't matter how many OEMs you have producing unwanted variations of it.
That is the problem.
Otherwise, I'd note that at no time was any promise ever made (implied or otherwise), that more OEMs would participate in the WP ecosystem. Just because the WP licensing model allows any OEM to become a WP device manufacturer, doesn't amount to a promise of that happening... the title is misleading.
P.S.
Note that while people here are calling for more OEMs, in the Surface threads people are calling for MS to abandon the 'good for nothing' OEMs and do everything themselves. That isn't necessarily a contradiction, but it sure feels like one...
