Of those description, whatsapp is the one that's actually the classic "how capitalism is supposed to work": provide a comparable or better service for a lower price.
Amazon's era of sales tax evasion is mostly over. And if anyone is monetising copyright infringement it's not Google (who are somewhat conscientious about this after some lawsuits) but Tumblr (literally made of copyright infringing photos)
Google (meaning Google.com, the search engine) is a flagrant copyright violator and the only reason they weren't shut down is that they became too important too fast for the judges to be willing to rule anything other than "Yes fair use works for everything they do, please don't hurt me for breaking the internet". Many smaller groups were shut down by Lady Justice for behavior very similar to Google's.
Lot of this is that Amazon has a physical nexus in most states or wants to. (And the situation with affiliates is murky.) So not much point in resisting at this point at their scale. Almost no other company collects sales tax for out-of-state sales where they don't have a physical retail location although buyers are theoretically on the hook for reporting it during tax season.
