For the most part, it doesn’t sound like these “bad” customers are doing anything illegal or in violation of TOS. They’re just exploiting offerings for something they wouldn’t normally spend any money on. To be surprised that they don’t stick around long or spend as much as non-incentivized customers shouldn’t come as a surprise to anyone and shouldn’t be seen as some kind of failing. They would not normally have used the service anyway so why moan when they use it for a little while and then stop?
“I was surprised to find out by making a trip to Silicon Valley to attend the RISC-V Summit and asking a lot of pretty naive and uninformed questions that chip manufacturing is just the big kid version of making a PCB for a science fair project.”
This seems like a little bit of a simplification to me.
