No, he's saying he had cheap coders creating cheap code.

Absolutely.

Of course not, why would you write “cheap” when you can write “h1b”? Referring to people by only the noun of their immigration status with no other information in no way has any reflection on how GP thinks about anyone based on their immigration status.

Yep, and what’s more, I’m sure that commenter is not referring to, say, ethnically German or French visa holders when disparaging “all those H1Bs” ;) I’ve learned to not be surprised by the persistent and nasty ‘community’ of these types of commenters here on HN, fortunately they’re not the majority.

An immigration status that's routinely abused to bring in underpaid workers to suppress wages; it's not a personal attack to say that those exploited workers will generally be low-skill, any more than stereotyping PHBs or management consultants or first-year students as ignorant is.
