I can understand your concern, but MTGO is a very different game. Some of this has to do with the shoddy interface, and some of it has to do with sitting at a computer. The latter is what I think you are missing.
When someone is sitting at a computer there is a nearly infinite source of information that they can tap into at a moments notice. There are number of advantages I'll specifically point to:
- I can google my opponent's name to find out what decks they play.
- I can look up a strategy guide, or my own notes in the middle of a game.
- I could be having conversations with other individuals.
- I could technically ghost my opponent if they are streaming.
So on so forth. Where do you draw the line? What is fair and what is not? I'm not quite sure the exact answer.
I recall there being a thread about infinite combos, whether you should scoop or not on MTGO, or let your opponent use up a ton of their clock trying to complete the combo. Is that moral? In paper, you would just be dead because there are rules to allow you to display a loop.
I've also had opponents get furious about a misclick that caused them to lose games. Should I scoop to my opponent who has made a misclick?
MTGO is such a different animal from paper, applying the same blanket rules doesn't seem correct to me.
What I will say on this particular topic is that I enjoy Vintage streams where I can actually interact with the player. As a viewer, I'd be much less inclined to tune in if I wasn't allowed to say anything about the game. The reality is that this a game, and people are playing it for fun. No one here in the Vintage community is making a living off just playing. I don't see an issue with people trying to enhance the fun of the game, and in fact it should be celebrated (as it usually is).
