I'd sooner call it vandalism. Restoration is what's shown in "They Shall Not Grow Old" where they paid attention to detail and approached it with respect.
Sharp edges and shifting red-blue colours is not what I would call restoration.
It’s not vandalism unless the originals have been damaged. If someone makes a digital copy and goofs around with it I really don’t see any harm being done.
It's getting sadder and sadder to see people enjoying these fake restorations. Eventually we'll have so much of a mess that the original source will be forgotten or lost.
