I don't read the news on April 1 because it got old decades ago. Sunsetting a service, rather than killing it outright, is a kindness. Making the announcement on April 1 means people will miss it or ignore it. Uncool.
“A few support calls” = At least a few companies who have unnecessarily faced major enough issues that they worked through internal investigations of many different pieces in the stack and then eventually decided to reach out to external support for GitHub, potentially having reached out to other vendors’s support because some PM thought it would be “funny”.
I don’t actually think it would cause any problems personally, but I’m astonished at the flip dismissal of a “few support calls”.
