Yeah, caution is warranted but what they tell does not give any reason for why reto would be a likely honeypot, and their post potrays it as such, by just pointing to changes being made to the source that are known for needing to be changed by the network operator.
Did you check coincards? Can’t check it myself right now, sorry for that, but I remember they have a lot of kinds of cards.
I haven’t used the service myself, but looking to do so. I know them by Privacy Guides’s recommendation, if that tells anything. They only recommend Monero for crypto, and Coincards for cards.
