It's complicated.
My take: that particular attempt at secession didn't succeed, but separatists are anything but sitting idle: they're constantly pressing to gain privileges, lying, distorting public opinion, and frankly breaking the law every so often.
Nobody's “oppressed” in #Catalonia.
The criminal separatist leaders are being handled exquisitely well by the government: they are raised to the level of legitimate political interlocutors, some of them were pardoned, and now a few others will see their sentences reduced by virtue of this change in the law.
It's all very disgusting, IMHO.
