Blockstream does support Bitcoin infrastructure development-- something much of the Bitcoin industry has failed to do, perhaps a company you work for and are concealing through your anonymous posts?-- but that is a far cry from a "majority" by any definition. E.g. in the last 3 months 58 people have made contributions to Bitcoin Core, 7 work for Blockstream. Sorted by commits in the last year, among the top ten, 3 work for blockstream (all founders of the company). -- just as we've done for the last 5+ years (the same group has been in the top 10 contributors pretty much the whole time).
Whats your actual allegation beyond pointing out that we spend some resources supporting the public infrastructure we all depend on?
