They have parents on a second layer (lightning network) that would run on top of Bitcoin and would make money on the transactions, effectively making bitcoin "theirs".
What specific claims of those patents are being infringed? It looks like that person just posted every crypto patent then could find. Also which of those patents do blockstream own? I looked at a few random ones and none were owned by them.
LN fees are optional and if blockstream wanted to charge them for facilitating transactions they would have to provide a service to make it worth while our the transactions would just route around them.
