It's effectively the same, except people volunteer or are paid to play test.
This whole industry really needs a lesson on consent.
Indie games don’t have a budget for playtesting, but they can probably swing a GA account.
There are games that let you opt-out, hell even ones that ask you when you first open the game. There are bad apples, but there are plenty of good ones too.
So long as personal information is not collected, consent is not morally necessary.
If I collect information on how often a coin-op Street Fighter II game is played in an arcade, while collecting no personal information, consent is not needed.
