Mike Judge just said it in this scene.
The goal is to inflate stock prices to absurd levels and make a ton of money all at once.
Securing Market Share is part of that strategy. The more market share they have the more they can impose new rules/standards that nobody asked for but cripples competition to follow the rhythm. Thus they also look like they're innovating while they actually do shit.
So not only they're inflating the true value of their "product" but they're also making it near impossible for a free market to exist.

If they'd stop they would look as if they're hesitating or in a bad position, and that's bad, as the stock value will go down.
Same thing happens when they keep pivoting. So to avoid to be seen as pivoting they invest in everything (these entities have the fund anyway).
Same thing happens when they keep changing directors or vcs dumping them. They can't be seen as if the project is in a bad spot.
