the thing with him is that he doesnt know much how to be diplomatic,the failed europe tour of around 2010 was a major turning point in terms of his career and what happened behind the scenes, the clashes you are talking about are about 6 years or so but in reality he already started hitting back ever since he left maison mere,he is too honest naturally and that is a "bad thing' in congolese music,our music seems to only tolerate big mouth when you have gone through a cycle of "politeness" to start,for exemple but na filet or fally robinho,they do get criticized but not as constantly as somebody like celeo or like innoss who came into the big game straight away with the "i wont be your walk over" mentality
both celeo and innoss tried the peace approach from the start but then they quickly saw things they did not like and could not play the game of smiling on tv and ranting in private
whethere you are his brother uncle colleague friend whoever he says things like it comes to him which is for example why about his first album he clearly said in interviews that ferre told him since he is an atalaku to invite singers of their generation including fally but he did not come anymore to participate once fally sang the first out of them or which explained how he's made peace with maison mere about 25 times because when he has something to say he does not hide it ,and as you said unlike celeo they balanced it thanks to the success of their music,but then there is surely a lot more behind that what we can easily see
for example i can certify you that on many tvs of kin his songs are not allowed to be broadcasted because ....
I think he had accepted a certain thing in 2010's maybe robinio would not have had a career lol
