Ever since Windows 95 I've had the Start Menu how I like it, you know what? I don't actually ever use it now. Windows Key + R for running stuff such as CMD or powershell, anything useful is pinned to the taskbar (i.e. Steam / Games and Office Apps). You can keep fighting it but, in the end, you'll find it's actually quicker to move on. Like in the old days I'd have Start Menu\Games\Game Name now it's just pinned. It's longer to go via the Start Menu. Even clicking the Start Menu and then the game name is more long winded that a single click on the game.
I get it's down to the way you want to use your PC and you have utilities, such as Classic Start Menu, that will enable you to have it how you want it and Windows 11 isn't stopping that. A lot of the telemetry you can stop in the installation but then you can get a firewall (such as Windows Firewall Control) and block all outbound, you can then just allow what you want outbound rather than everything. It's not a perfect but every company out there, such as Google and Apple, have been doing this for years. If you don't want it then you have the options to stop it but you just need to put in a little work. Hell if you want to completely stop it then there are a ton of telemetry apps out there:
