Failure to live up to promised quality of service is one obvious "evil" to be added to the article. ISP does not even have to be "deliberately" evil to underinvest in their network and oversell their capacity. Measure your latencies and actual bandwidth throughput and often you might smell a rat. This is not even necessarily by malicious intent, the infrastructure of ISPs could be sufficiently complex that some subtle mis-configuration somewhere in the upstream router could kill your performance for certain operations. ISPs act as Internet gatekeepers and have enormous power over its clients/users. With this great power should come great responsibility.
