Valid question.
Web comics are just comics on the web. Tapas is known for its condensed, quick formats, but originally that wasn't necessarily the case. Personally, I've had my account for about a decade, and within that time frame there aren't just many platforms that support the traditional comic format. For example, SmackJeeves does not have a mobile app, which greatly affected its readership and platform. Of course, there's platforms like Medibang or various manga readers, but sites like those are often decentralized, have software restrictions, and/or don't offer room for indie creators to grow. At least with platforms like Tapas or Webtoons, there are variables that can be more equitable.
Also, I don't get the TV to movie analogy. It's not like general audiences get the original resolution; only projectionists and theaters get a copy close to the original, and even then it's slightly reduced. It's more accurate to say Streaming vs DVD because of video codexs and international distribution. But in my opinion, the text in traditional comics and mangas should be scaled no differently to the text you'd read in an article or journal on mobile.
If you find these types of posts (I assume "print comic makers") baffling, I hope this comment gives perspective on a niche that compels enough people for you to notice.
If you're willing to entertain my question, can you provide feedback on this page? This is my wordiest one so far, and I plan on keeping the threshold at this point. I'm not being antagonistic, I want genuine feedback.
