Precisely the type of ads we should be celebrating since they subsidize the content we consume. A lot of people either are oblivious to their actual importance, or just don't care. The internet simply wouldn't be what it is today without them. True, there has been plenty of bad (trackers, malware, etc), but the good that has come from that subsidization has lead us to where we are today. A vast majority of the innovation on the internet has been directly or indirectly related to that subsidization.
