I was reviewing GCP's Free Tier today, they have the same approach, if they need to change or drop services they agree to give 30 days notice, same as Docker did. It's probably common for other cloud companies offering free stuff as well. All the negative attention Docker received was fully and wholly undeserved.
Google is notoriously bad about this and gets negative attention from it, so the comparison isn't favorable, and the publicity is still wholly deserved.
Do you mean Google or GCP? We don’t see complaints about AWS because Amazon closes Dash buttons or Spark, and also Azure is not seen in any worse light due to Microsoft discontinues Skype and what not.
Can we name one remotely popular service of GCP that has been shut down at all?
Until then, I maintain the Docker publicity is undeserved and if I had to guess, was brought on by podman astroturfers who have been polluting the web the past 2 years claiming how great podman is.
