In the past, many developers were against copyright law because they saw it as a way for big corps to stifle competition and curb creativity in order to increase their profits. A lot of people right now invoke the violation of the same copyright law because the tide has changed and now companies, by ignoring copyright law, are hurting artists/smaller companies and/or not contributing back or unlawfully closing the code in the case of GPL.
I don't see any kind of hypocritical stance here honestly. All this time the criticism of the enforcement of copyright law or now the lack of it just reflects the fact that some people are genuinely concerned that bad actors(big corps) are using the law to damage society in order to pursue their own interests.
