The idea that someone would reach out to you and actually expect that you would take something down because students were using it is absurd. It shows a lack of understanding of both how the internet works, and more so the idea that an action like this is really improving the outcome of the students. If the student outcome depends on you taking something OFF the internet, that is the problem.

The pricing differential is just absurd now. I expanded the memory on my math clusters about 2 years ago so I would have 4 machines with 1.5TB of DDR4 memory each. Back then a 128GB DDR4 DIMM could be found for $150 used. Now those same DIMMs are $600-$800 used! I think the RAM in my homelab is worth more than all of the other hardware combined.
