So, no, it's not like any Linux distribution bundling a third-party browser like Firefox or Chromium, since none of those distributions have a monopoly to leverage to start with.
Surely, you'll at least need a decent web browser to get online to download a different browser of your choice, no?
Go to store, by a CD with browser, install. The age when boxed software was a major thing extended past the point when IE started bundling IE.
Of course, with a TCP/IP stack you can get software from the internet a lot of ways without a web browser, too. FTP was a thing, after all.
If you just bought your first computer at that time, you weren't likely to have internet service to connect it to until you bought that separately, and when you did, you would have software, too.
[1] Although admittedly the last real work I did in Windows was 7, so please correct me if the situation has changed.
I'm pretty sure I've seen the dialog in Windows 10 as well, but not for Edge, which I find even worse than IE.

The short version is that the actions of a non-monopolist are looked at very differently than the actions of a monopolist.
Additionally, you're dead wrong about "every Linux distribution", and even if you weren't, the fact that there are many of them would moot an antitrust argument.
False. See, for instance, Arch.
