Yes, but that would be “Nintendo are an awful company”, not “Nintendo are awful companies”.

That being said, I have absolutely no idea why the other commenter thought this was related to gender identity and pronouns.

They were probably bringing their overly sensitive dislike of a cultural point of view into it when none was intended. They probably should have considered that HN is a broad community. As such they would know that HN has non native speakers. They would have realized that their interpretation was likely off the mark for this or another reason. They should have more charitably interpreted it as a typo and they should also have realized that their viewpoint on the singular use of “they” was inaccurate since they have probably heard such usage their entire lives but only now, in recent years, are they are just beginning to listen for it. They probably are not aware that this usage extends back long before everyone currently alive, but I guess this is new information for them. But now they know so hopefully we won’t hear such comments from them again.

Going to guess you don't consume a lot of foreign media? This is a difference of regional language use in English.

American usage would have "Nintendo is an awful company". British usage would have "Nintendo are an awful company."

This is specific to nouns like a company name that represent groups of people.

This difference surfaces a lot in news reporting about companies. You may have heard the following in an English accent: Apple have announced a new iPhone ...

1. That seemed to be a pretty obvious typo, no need for the snark

2. Why did you feel the need to bring gender into this

3. The singular they has been used for centuries, see also https://en.wikipedia.org/wiki/Singular_they

“They” has been a very common usage in a singular context for a very long time, certainly during the 3+ decades that I’ve been educate enough to even know what a pronouns is. This usage dates back the better part of a 1000 years to the 1300’s

Formulations like the following are common: “Bob saw someone shopping for the Dolphin emulator in the steam store on their computer. They couldn’t find it though because the litigious corporation Nintendo had sent a DMCA takedown notice.”
