As the Terraria developer showed with Google Stadia, even if you're actively developing software for their brand new products you'll be ignored

I managed to get in touch with a Google engineer once for help with some Adwords API stuff (our company is a large adwords agency).

...They accidentally CC'd in a public mailing list into our discussion and leaked enough information that someone would be able to use the automated support system to change the company AdWords password. There was basically no way of contacting anyone further, the engineer couldn't contact anyone that could help us. We ended up making a new adwords account.

I might as well been the engineer that reached out toward you. But in the end, I was let go as support is not earned any metric into performance.

I did run into that engineer in-person at a Google event and grabbed a coffee with them. I think they're still at Google. No hard feelings but yeah getting any real support at Google is impossible and obviously not prioritized by the organization.

I don't think that's true - Google One (which I subscribe to basically just to have a support fallback) offers this: https://one.google.com/about/support?hl=en_GB

"Live chat, email or call us".
