Okay so the 2015 EOL ones, yeah I can understand telling the customer to update their shit. They shouldn't have to support nearly 10 year out of date stuff.
I would love to know when they stopped selling it compared to the EOL. EOL should be at least 5 years past the last time the models were shipped out, maybe more. So if May 2024 was EOL I sure hope they weren't selling them after 2018.
