in my experience DeepL has the best results for some language pairs while Google is better for others (and has a lot more languages).
But, these days I'm happy to say Firefox translate is the first thing I try and it is often sufficient. I mostly only try the others now when the Firefox result doesn't make sense or the language is unsupported.
What the people here saying this "seems legit" are really saying is that, if the site is providing DRM content which you want to see, then it is indeed using this for its intended purpose (which is to prevent you from recording and/or retransmitting the stream). This is true, but, it doesn't mean that the site isn't also collecting your device identifiers and using them for some nefarious privacy-invasive purposes. And of course, they most likely are.
So if I were you I would look for a pirated streaming website instead of running this proprietary software to watch a DRM'd stream. (The pirated site will probably also be privacy-invasive, but they won't get your device ID... and you're more likely to be able to block its ads.)
