I wondered if that might be the case, but they're writing in English which use a comma as a thousands separator; in which case, they definitely have the decimal point in the wrong place, even if it's down to a grammatical error.
I'm not so sure they're separate, or at least that they should be treated as such. Either way, it's a shame that this isn't standardised, regardless of the language spoken. Likewise units of measurement (weight, distance, time etc.).
I can set my language, and separately I can set my regional format which encompasses things like which decimal symbol and which thousands separator to use (both offer the comma, the dot and '), how dates are written, which day is the first of the week, how time is written (12/24h), whether to use Arabian numbers or one of the other digit-based systems, which unit system to use (US or metric) etc.

It kind of is: The International Bureau of Weights and Measures has maintained since 1948 that you shouldn't use dots or commas as thousands separators. ISO 31-0 prescribes the use of small spaces, and so do various other American and international standards organizations. It's just that this is widely ignored.
Let me tell you about the pain of CSV-files that use ; as a delimiter because otherwise you couldn't use decimal numbers.
Or in office documents where MS "translates" commas. That means you also need to replace all , and ; if you translate office scripts from English to a language with other decimal rules.
Nevermind the parsing of numbers in general... That stuff can crashes moon probes.
In school (UK) we were told to use ' as the thousands separator in mathematics as it avoids confusion i.e.
1'234.56
1'234,56
Either of these can be understood no matter which format you're used to. Although, I don't think it's ever caught on really (or whether it's even advisable/sensible).
