I don't know who criticize, but I support use of native languages on Steemit. And I send relevant texts in two languages, like these:

https://steemit.com/economy/@lighteye/bitkoin-i-predstojeci-raspad-eu-tachke-sloma
https://steemit.com/economy/@lighteye/bitcoin-and-the-imminent-eu-fallout-breaking-points

Google translate is still far from perfect :)
