That's international English (lingua franca).

I find it fun when native speaker complain about ESL speakers, since in the end it is likely that international English will win.

I live in a non-English speaking country, the common language in the office is international English (there are 60+ nationalities, and less than 20% are native english speaker). It would be fun to track over time if the native speakers start speaking international english :)

The ESL-voice was part of the charm. It adds a note of authenticity. :-)
