Sometimes there are really-free things. Old-style open-source software is a collection of such things. Extensions, at their beginning, were too, and some of them still are. As far as I know, for example, there's no 'gotcha' in uBlock Origin (although there is the 'gotcha' of knowing to look for them instead of the myriad other solutions that are non-free).
