As a normal student doing a single undergraduate degree you were never really aware of how much your course cost but the University was certainly getting a chunk of money from the relevant Government department - whether you call these "tuition fees" isn't that important.
Scotland has had a tradition of meritocratic access to Univerities that goes back a long time - within that context having fees paid for by taxpayers doesn't look that odd. Certainly I benefited from it - I came from a low income family from the rural North of Scotland and all four of my siblings and I went to University/College.
Hypothetically, assume that there were already tuition fees in Scotland (without equivocating between fees paid from "relevant Government department(s)" and tuition fees) and that the government had just announced that they would not be increasing the tuition fee. Would it be more accurate to say "Scotland says tuition fee increase to be met by taxpayers, not individual students."?
Saying that recent increases in the costs of higher education will not be shifted from the taxpayer to the individual student in Scotland would be fair. Saying the taxpayers are supplementing themselves is nonsensical.
