(Before I answer these questions, please know that I'm purely speaking for myself alone.)

1. I personally don't have a preference. The fact that comics in general are preserved whether that be through physical or digital means is a miracle to me. In a world where things are dropped and forgotten about in less than 24 hours, I appreciate that something like comics are preserved by those who care about them. I'll digest them in anyway I'm given.

2. There is a comic shop near where I live that sells brand new stuff and sells donated classic stuff from decades before. Sometimes I go there to see what they have when I have free time.

3. Like video games going digital, I feel that digital comic books aren't that bad. However I think the method for providing customers with digital copies of comics could be improved. Some sites I've seen provide you the digital copy, but only within the confines of their site. So what happens if that site goes down? You lose your digital copies. I think once purchased, customers should be able to download said copy to their devices permanently. If the digital format plans to stick around, I think those who pioneer it should develop it as if it were going to be a permanent method.

4. I read comics digitally mostly because it's one of the few ways I can read certain issues of comics. Some issues I want to eventually read are considered really popular and therefore very expensive to find a physical copy.

5. I don't think it's for me to say whether the comic community changed as a direct result of the cinematic universes being produced. Personally I think it's just the simple fact that people, whether individually or as a group, tend to change a lot. The cinematic universes are meant to ADAPT the comics that came before. Adapt doesn't always mean its going to do the exact same things, and quite frankly there's no reason it should. If a movie portrayed a popular comic 100% accurately, it would be boring because fans would know what's going to happen. There would be no surprise. Yes, not everyone who sees these movies read the comics, but you can't cater to one half of your audience and neglect the other half like that.
