This is not the first time that CG has declined to offer the 5 shards to WebStore participants. The first time might have been Padawan Obi-Wan, but I don't remember for sure.
The important part is to recognize that you can no longer count on those shards. They are as they were originally -- bonuses (when they appear at all), not expected and budgeted aspects of the shard economy.
I, too, felt that was petty, but I got over it. That was special, this is normal. For anyone who wants to have fun playing this game over the long haul, you have to make peace with this kind of thing.
