On the fees issue, without getting into the argument, certainly the real question is the total being charged-if in fact its just renaming a fee and we're being charged the same amount as before, economically its the same. However, optically, its not a great idea-emailing of the tickets takes minimal, if any human involvement or other things that drive up a ticket vendor's costs. It essentially makes it look like the customer is being charged for a computer to find your tickets and email them to you. There should always be a way to get your tix for free- including for those of us who don't live in NYC and can't run by the box office ahead of time. If memory serves, in the pre-email days they'd MAIL you the tickets for "free" (ie as part of the standard handling charges). I can understand charging for mailing things these days, but e-mailing is a different thing all together.
As to paperless tickets, I do understand that in the current situation, there are good reasons for "contactless" ticketing and ticketing collection. I actually liked the pre-Covid E-tickets since you could always print them out again if you misplaced or forgot them (they weren't as "nice" a keepsake as the old tickets, but could be kept with the Playbill and were made to "look" like the old tickets). Certainly the option of having access on your phone is helpful and one less piece of paper to keep track of. But as others have said, not everyone has smart phones (though their numbers are likely dwindling) and e-ticketing requires multiple apps. Its also easy to forget or even lose your phone. Even if one wants to argue the person who forgets/loses the phone is to blame in such a situation, phones also malfunction. My (less than one year old) phone died a few weeks ago, Luckily under warranty and was able to get it fixed but what if I pulled my phone out as I was going into the theatre and that happened? It took a day at the Apple Store to get it straightened out.
My "return to Broadway" weekend includes one show each in Shubert, Nederlander, and Jujamcyn theatres (and thus one each for Telecharge, Ticketmaster, and SeatGeek). Ticketmaster and SeatGeek are electronic only and I had to download the app to make sure the ticket was in my account. Telecharge said they'd email them to me for free when we get closer to the show (I'm going in early November). It'll be interesting to see what ends up happening for those.
