First of all it's not just so easy to destroy infrastructure in a way that can't be rebuilt quickly; thousands of miles of train tracks would be difficult to destroy. This is happening all over Ukraine.
Second, blowing up your own country's rail infrastructure means you can't use it, either, which means you lose an advantage you have that your trains can move on your rails but your enemy's cannot.
Finnish rail roads are mostly north-south bound (or west of Helsinki) which are not helpful to Russian advances. The only way for them to transport weaponry would be through east-west bound (near the border) and there isn't many. It's easy to take such out and they would not impact our infrastructure at all as they're not heavily used (if at all since eastern part of Finland is economically the weakest link anyway).
It's quick and easy in the end to destroy. Rebuilding them under artillery fire isn't easy.
Also I really can't think of the way Mac's mouse settings in WoW work better than the Windows ones. Scrolling, mouse movement are all having more settings under Windows to customize them compared to the experience on Mac (even with all the tools such as Mos to help with the bad external mouse handling in Mac).
So what exactly is so superior? I play WoW on both platforms and when I have a choice (that is, when playing at my home desktop - on my summer cabin I only have the Mac option) it's always the Windows one I select. It's nice that it works in Mac so I can play everywhere as I only have Mac laptop, but the sometimes weird graphics bugs, worse performance and odd issues with rendering displacing my WAs and other stuff just doesn't inspire confidence in Mac gaming compared to using Windows. And the mouse movement.. ugh.
