Has country music been poppy since the 90s?

  Actually it goes back farther than that with the pop sound. The real start of the pop sound in Country music actually has it's roots in the late 1950s and early 1960s with RCA studio B in Nashville. Although considered one of the great guitarists Chet Atkins along with Owen Bradley, Bob Ferguson, Bill Porter, and Don Law, were to be largely considered the main architects, of what's known as the Nashville Sound, that would make Country music, to have it appeal to the adult pop audience, or more for those in urban areas, and now what's called suburbia.

yep and it sucks

Yes but not every song as well as the fact they where still good songs. There are still good songs but many do suck because it sounds like pop. I like most of Shania's songs with the exception of one for reasons we will not discuss again. Rascal Flatts has some good ones. Lonestar is really good and many of his songs are not pop though some are. Even Taylor Swifts early country songs where actually pretty good sounding. But there was still a lot of country into the 2000s as well as country rock and other things like that.  Country has been downhill for a while since they are trying to make it trendy.. Though again I do like plenty of new songs but I don't only want to hear pop country. I will put it this way if I want to listen to country then I want to listen to country and if I want to listen to pop I will listen to that. 

yes and now more like rap

Some of it does, but not all of it.

Country music has largely moved on from the three chords and simple lyrics of Country & Western and is now more country pop or country rock. Some people refer to newer country styles as 'Americana'. There is still plenty of old style country and a wealth of styles in between so no one is missing out. There is just a wider range on offer than there used to be.
