I don't work at TA, but I do own a tiny hotel in France so I deal with Booking.com and TA rather frequently -- TA does have a paid product for hotels, however other than not having my website URL and the ability for people to book directly with me on my TA profile, there has been absolutely zero difference in our visibility on TA. So far, TA has been really nice to work with despite me not paying them anything (yet.)
TA is definitely my go-to app when I go places; it is pretty good both as a consumer and as a listee.
I found TA invaluable for researching trips to Italy, Israel, and Costa Rica. You definitely have to use it carefully, and I verified with other sources, but there's a lot of good information there.
