Outdated MAterials

I have signed up with StationX based on the good reviews available online. But I have noticed that some of the materials are referred to in this course are outdated. Like the use of Word 2010. Based on the course update is showing that this was last updated in 2020. Am I wrong to say that this is an outdated course and does not live up to the security threat we have now days? or the course is worthwhile taking?

95% of certificate courses are up to date with the latest certificate. 95% of none certificate courses are up to date. We are updating courses as a weekly task and adding new course all the time.

Older apps and OS are very prevalent in businesses too.
