I feel like this is sour grapes on HTC's part, they need to spend less time worrying about what Samsung is doing and more time getting their house in order. No matter how I may feel about Touchwiz Samsung has managed year after year to sell phones. They are literally the only Android manufacturer able to compete head to head with Apple.
HTC needs to find a way to capture the community. The M8 and M9 are almost there but lacks that quality to make it special. I personally think HTC needs to find a niche market as Samsung has captured the average user. HTC should focus their brand in a direction that captures an audience. An example would be to make a phone that the community has been begging for and that is a phone where you can switch from vanilla android to Sense depending on the user. Users who want an unlocked bootloader and quick (nexus like) updates flash the vanilla version where users who want a polished custom software wait on HTC. They could also open the market to themes users can install on the fly. Root users have a soft spot for HTC so they should capitalize on that. Go Google style where you can lock and unlock the bootloader with ease without the "tampering" warning or having to input your information through the HTC site.
