I don’t mind it either, they need some way to finance the development. However I wish they would make packs of older DLCs and sell those cheaper.
For example in Europa Universalis IV you need a whole bunch of DLC, and buying seven 5 year old DLCs for full price is just not very appealing. Sure, you can try and wait for sales but they are not always available when you want to get them.
It was probably used for spam in the past, so they added a rule to trash all links to that domain.
