"infinite scaling" means _exactly_ that. If you don't want people to use accepted dictionary definitions of words like "infinite", you should not use them in your marketing.
A few telcos here in Australia have recently lost court cases about their use of the word "infinite" in their cellphone plans/marketing, and then cutting off or charging extra to customers who "used too much". The court, rightly in my opinion, said that the meaning of the word "infinite" is clear and well known, and any claim that it included "limited, of course, by common sense" is bogus. Be careful of letting your marketing team write too much hyperbole - occasionally you'll be held legally accountable for it.
I suspect if the amount in dispute had been an order of magnitude or two larger, Jacques may well have had a strong enough case to find a no-win/no-fee lawyer to go into bat for him... I know I'd prefer not to have to explain to a judge how those first two boxes in the first column on the WPEngine homepage didn't cover all of Jacques complaints.
This comment sounds like one of those BS ISP ads where they promote "Unlimited" serviece but it's not unlimited bandwidth only an "Unlimited" connection. Or how about the cell phone providers offering "Unlimited" data where there's a star at the end and it states that you'll be throttled after 5 GB.
You have to understand the layperson won't know anything about tables etc and stating "infinitely scale" is a HUGE selling point for potential customers. If they wanted to be truthful they wouldn't say that, or they would say we CAN provide infinite scaling IF the following conditions are met.
