No, it has nothing to do with the Chargers stinking. Because many teams stink, but the Chargers are the ONLY team that pulls these shenanigans.
I don't really know anything about Bosa, but can you tell me why he alone deserves to make this concession out of all the first round picks since the current iteration of the agreement in 2011? Why should he be singles out? This year's 4th, 5th, 6th, 7th, etc. overall picks didn't have to concede this, so why should he?
No it DEFINITELY has to do with the Chargers stinking. As I said and you edited out: if the Pats were doing this it would be considered an example of how much smarter they are than everybody else.
They are NOT the only team doing this. Those clauses are STANDARD in contracts for players drafter after 10. For whatever reason top 10 picks only generally get 1 of the 2 clauses. Why should the top 10 be singled out? Players 11 through 253 signed contracts with both clauses, why shouldn’t the top 10?
