Here is a thread you can use when you go on a tangent out of the scope of the original discussion. You can also start a new one, say in this case on the topic of “should people celebrate and mourn the loss of trig systems”.
On the matter itself, regardless of what you think people should feel about it, fact is a lot of people’s homes were at least changed, and in many cases destroyed, without their consent. Even if the you think the change is for good, it was done without consulting them, by force. The people who did not want it have all the right to feel something was taken from them, and to mourn, and to be angry.
“Rejoice, for I have Reclaimed you for your own good” is a line the Minmatar are intimately familiar with.
And we are not buying it this time, either.
