You aren’t interpreting this correctly, they are indeed eliminating all tuition, not just the fees.
Admittedly pedantic, but they are not wrong.

> (Canada, US) A sum of money paid for instruction (such as in a high school, boarding school, university, or college).
> Synonym: (UK) tuition fees
Slater's correction may still be fair, despite the context of this being an American school, because it's a headline from a British website..
Do you have a source for this? I am reasonably sure that in American English "Tuition" can certainly mean the fees you pay to be taught.
Tuition = the money you pay for your schooling, I.e., credit hours.
Fees = Costs on top of tuition like registration fees, application fees, and other miscellaneous charges that aren’t represented in the per-credit hour price of school.
If you told someone in the US that their school was eliminating fees they’d take that to mean that they were getting a small discount on a still-very large cost. Think in the realm of $30-100 per semester.
American English has basically detached the word “tuition” to have anything to do with the teaching.
