You can send Swift Playgrounds apps to other people over messages. To pick just one example, from what's often the main target of these "LOL these aren't real computers" sorts of complaints. If you're on a desktop, there are tons of ways, most more accessible than Back In My Day. I do think we lost something when Flash in particular died, but less apps/games (there are... a lot of very, very indie games made these days by solo hobbyists or enthusiasts, check places like itch.io, it's an overwhelming number) and more the independent animation scene, which was huge during the heyday of flash but seems mostly dead now.
