They wrote, "all links will continue to redirect to the intended destination after March 30, 2019".

Other than that I agree on all your points.

They have hidden important info about the validity of the AWS credits. So it could be many years or it could be just 1 year, as long as you're subscribed to Product Hunt's Ship.

A screenshot, just in case if they change their mind:

I'm interested in knowing more about details - where you able to locate them?

Hi, it was just a comment from @jakecrump representing Product Hunt's Community Team, he confirmed they are valid only for 1 year after activation: https://cards.producthunt.com/cards/comments/589842

Did you find it? Can you post a link?

It was in the comments section of this announcement post: https://www.producthunt.com/upcoming/ship/messages/how-to-ge...

Other than that no any other information.
