If the market is working without or with little friction, it shouldn’t matter whether BCE funds projects with BKC or BKS sales.
In the first case BKC revenue gets used for funding; BKS value is negatively affected, because dividend payment is reduced.
In the second case dividend payment goes on, but BKS get diluted; BKS value is not negatively affected by reduced dividends, but by the dilution.
As development/marketing/etc or money costs money, BCE needs to sell either BKC or BKS to fund it.
If the development/marketing/etc is assumed to earn BCE more money1 than it costs, it makes sense to go this way.
You need to invest money, if you want to earn money 
…but I don’t know whether the market is working without friction.
In the end BKS holders may decide which way to go, because it’s their financial responsibility 
That!
