I don't think these services will affect Torrents in a significant way.
I know people who have Amazon prime,yet torrent some shows because they are censored heavily in my country.
Also, nflx doesn't offer some movies I want In my country, so I use torrents and haven't had any noticeable problem regarding seeds.
