A lot of crapware is now set stop that their bringalongware installs by default unless you UNcheck it, plus they intentionally make it confusing so it looks like you’re accepting the thing you wanted. Scumware.
I’ve noticed that, but I’ve been quite careful to look closely at all the options and open every tab to make certain I always Un-check anything I did not wish to be installed.
For those few that did not provide an option to uncheck something so as to not install it, well, that particular program did not get installed.
