As the business matures then the capital gains get realized and the original backers are replaced with the rent seekers looking for dividends higher than they can make on the money market.
BSA prospered while the original gunsmiths were the board members
As they resigned they got replaced with the money men who knew nothing about any of the things BSA did apart from make money .
Had ther not been a WW I & WWII BSA would have vanished long before they did .
In theory the entire shareholders own the business & the directors are there to oversee the running of the company on behalf of the shareholdes in general.

The board members when these sales happened all had direct links to the owhers of the companies that BSA was buying.
