Around the same time, Kaspersky, the Russian anti-virus company, wrote a blog post that warned people about this specific app. It was framed somewhat misleadingly - "reading, deleting and modifying the data in your phone's memory" would probably be interpreted by most people as something other than "the ability to modify data on your phone's external storage", although it ends with some reasonable advice that users should ask why an app requires some permissions.
So, to that end, here are the permissions that Kaspersky request on Android:
Every single permission that Kaspersky mention Meitu having? They require it as well. And a lot more. Why does Kaspersky want the ability to record audio? Why does it want to be able to send SMSes? Why does it want to read my contacts? Why does it need my fine-grained location? Why is it able to modify my settings?
There's no reason to assume that they're being malicious here. The reasons that these permissions exist at all is that there are legitimate reasons to use them, and Kaspersky may well have good reason to request them. But they don't explain that, and they do literally everything that their blog post criticises (including explicitly requesting the phone's IMEI). Why should we trust a Russian company more than a Chinese one?
The moral here isn't that Kaspersky are evil or that Meitu are virtuous. It's that talking about application permissions is difficult and we don't have the language to explain to users what our apps are doing and why they're doing it, and Google are still falling far short of where they should be in terms of making this transparent to users. But the other moral is that you shouldn't complain about the permissions an app requires when you're asking for even more of them because it just makes you look stupid and bad at your job.
