however well intended, the same company that sponsors Bitcoin developers also mining BTC is a conflict of interest. It's a good thing they're not the only organisation sponsoring developers, but I still would prefer that this had not happened.
I don't see any problems here. I like the fact that the 5-6 exahash they added lowers the dominance of Bitmain's mining pools, and this is just a start with how I expect Blockstream to keep increasing their hashrate.
All the anti Blockstream propaganda comes from the Bcash camp-- they do not control Bitcoin development nor have they ever done so. I wish them good luck with the future contributions they have in store for Bitcoin.
I have never tried Blockstream satellite, but when I have some free time and the right equipment, I'll see how it works and have a geek-out moment. They added LN support too so I'm kinda looking forward to it.
