I feel like it depends on your translation and how you define “free”.
I like to compare it to the differences between expenses and costs. Which is something people often confuse. Expenses are talking about the outflow of money and costs are talking about the effect of it on the bottom line.
“Free” education is free, because it’s not an expense it can be considered and indirect cost. It might never be something that is paid if you never pay taxes for whatever reason.
People also consider their social security income free because they don’t need to do more for it than filling in a form often online
You can buy office separately these days again. Not sure if Libreoffice is feature complete these days, but last time I tried it, it was missing a lot of the more advanced featureslike Solver/Powerquery/certain advanced formulas.
I recommend it for everybody and if it is not for you, you wil realise it in a couple of minutes of working with it if you are a oower user
