Honestly it loads fast, looks clean and has all the info I would need from them. I can't complain. Source says it was built using Trellix Site Builder.

I'd rather have sites like this than stuff full of bloated JS frameworks and trackers.

Lmao they have a different font and text color on every single page, what are you talking about? It looks like absolute, pure garbage. I would never want that to be my company website if I was a CEO, even if my company did just support systems that are 20+ years out of date.

Honestly, the more I look at this, this may be the worst website I have seen in quite a few years. I can't believe this is a currently-existing tech company.

That's like refusing to work with a dentist because he drives a beat up old car, or with a mechanic who's got crooked teeth.

What does the ability to create a "modern" website have to do with their ability to maintain a legacy database?

Because to most people appearances matter and that website (or a beat up old car) doesn't speak to them having their proverbial shit together. Maybe that's not your case, but I wager that's true for the average person and therefore to the average consumer.

The HN audience is probably strongly correlated with the minority of people who think appearances doesn't matter as long as it gets the job done.

Please note that I'm not saying one of these outlooks is better than the other. I'm just saying most people care about appearance for better or worse.
