In the other post I gave a reason not to wholeheartedly hate Crunchyroll, but with licenses it's easier to get the monopoly (nowadays it's oligopoly in the strict sense of the term) of audiovisuals. Enforcing exclusivity of emitting/distribution rights in several translated languages makes mostly impossible having new competitors, since native studios/producers only care about the contract they sign with whoever buys the rights so it's really unlikely for them to refrain selling them to a successful (in terms of producing money) enterprise. If any other platform/TV channel/etc. wants to emit it in any of those languages, they need to pay for distribution to Crunchyroll even if they don't use the same subtitles and stuff because they own the rights in those languages, and there are a bunch nowadays (the rights can also be bought for zones/countries, making it harder for other languages to emit said series by themselves, without having to pay for the intermediary).
What bad practices CR has? First of all, taking down series once they're no longer profitable without the chance of anyone picking them later because they may even still have the rights and making users pay the same amount for less content if you do not belong to the 3 English countries. Related to this point, there's a huge % of series that use a second-hand translation for other languages that are not English. Secondly, even for this lower quality service users have to pay the same amount of money for less series depending on the country you reside, and this amount can be even half in some cases for new series and mostly none for old series. Thirdly, it is known for many years that CR reduces video quality (for some series drastically) of the series and movies despite labelling with the same said quality (480, 720, 1080). Lastly, the use of MTL and AI is on the rise to cut costs and that result in terrible subs, for this season everyone knows how it was for Shikanoko. These are the main points, but you can find more controversial points if you surf the net.
Of course, rotten capitalists don't care about this because if they want they can pay for anything while laughing at non-rich people problems.
