Rule of thumb:

- If it’s a company doing an NC license, probably best to be careful because they can make your life hell with lawyers.

- If it’s a random joe doing an NC license, feel free to ignore it because they don’t have the money to defend it anyway. Especially so if it’s CC-BY-NC-ND, people that pick that one are especially likely to be in the all-bark-no-bite category.

At least that’s how one of the companies I worked for treated CC licenses… I don’t work there anymore.
