I don’t want to use Twitter in a tab.
I’ve said it before and I’ll say it again: Websites, wrapped web views, react native, et al solve a developer’s problem. They do not solve any problem I as a user have. They make things worse, the only question is how much worse. How much better are you forcing me to pay? How much cognitive tax am I paying?
I mean, webapps obviously have a positive value for you over the alternative of not using the service—otherwise you would be doing exactly that (and maybe using a competitor's service.)
At least personally, I appreciate first-class web-app versions of apps (with or without wrappers), since I use a not-very-popular OS and web-apps are basically the only way any company is ever going to give me a version of their software I can use.
That's a pretty broad statement. As a user, I hate installing apps. They take up disk space, and then I need to remember to remove them if I am not using it.
Also as a user, I am not sure how much additional security holes are created by installing a third-party binary. With a webapp, there is only a single source of security issues (browser).
