Good company but going soft - Avis employé Senior Software Engineer MathWorks

This is a good company that has gone soft in the recent times and resembling a big corporation with rampant inefficiency. Given that the company is profitable, there do not seem to be revenue pressures on anyone. Coming from a startup prior to joining MathWorks, I am constantly surprised at the lack of accountability everywhere. In engineering, one can work on a feature for any length of time as long as the appropriate specification documents are generated on a regular basis. There is also a huge difference in the quality of engineers from one group to the other. Unfortunately, the groups that harbor mediocre engineers have mediocre leadership that is so entrenched because of their long tenure that this inefficiency gets protected and even nurtured. Outside of engineering, there is even less accountability. There seem to be many jobs where people just show up at meetings, do not contribute in any meaningful manner and leave at the end of the day. You see them showing up at work at 10 and leaving at 4. Such sights are highly demotivating to a young, hardworking newcomer and makes it hard to pump oneself up for superior performance. There seems to be quite a bit of abuse of flex-time where people claim to work from home. It makes marginal sense, if this is a software engineer who can theoretically do coding over VPN. However, you see those whose job is coordination (program management, usability, marketing) claiming to work from home on a regular basis.
