Anti-consumer, to me, is a practice that leaves me without options or choices. I know that's vague, but to give a better example:
When a company buys out competitors to corner the market, that's anti-consumer.
Alternatively, practices that force the hand of the consumer in particular instances are also poor, and can be considered anti-consumer. This includes things like timed exclusive DLC for particular platform users or demographics (subscribers, etc). Things that effectively put one consumer in a different class because they spent their money in a particular area. It's not necessarily "anti-consumer" in that you still have the option to simply wait or not support that kind of behavior, but at the end of the day: it sucks.
