> Slack is legally obligated to provide Slack accounts to people who pay

Rather, Slack agrees to provide accounts to people who pay and agree to the contract in return.

That little stipulation is exactly what is in effect here. Slack believes the users are in violation of the agreement, and under the legal rules that Slack established and controls, they enforce immediate termination.

> if they are terminating accounts based on ethnicity

This defending of the argument based on wild assumptions that Slack is ethnically profiling is a bad place to start from. That hasn't been shown, nor is it very likely.

On the other hand, Slack is legally obligated to block traffic to Iran, and it's within reason to assume an account that ever had any traffic in Iran broke the law. It's certainly possible that Amir forgot that he used an Iran proxy, or traveled there. It's possible that someone on his team broke the rule without his knowledge. It's also possible that Slack made a mistake, which can and does happen from time to time at many companies when trying to enforce international laws using only IP traffic logs. None of that points at Slack intentionally terminating accounts based on ethnicity.
