It sounds like (guessing based on phrasing) ameen is the only, or only senior, technical staff member? Why would they let them go? If I were a cartoon-villain, mustache-twirling higher-up for said company, what this post tells me is that the situation is currently working, that my employee knows the score, and they don't seem liable to do anything about it except complain on the internet. In a really evil way, wouldn't it be reassuring to them?

I should be clear, I sympathize with the situation and hope that ameen's employer is not cartoonishly evil, and instead would maybe even realize they have improvements to make. But just thinking about possible outcomes of someone venting on the internet, firing doesn't seem like one that makes any sense.

If they are such a central team member to an ecommerce operation, likely the company feels equally stuck with them (e.g. how many sales would be lost if the site went down while looking for a replacement, and would the company even survive that?).
