Google is almost a 2 trillion market cap company. Docusign is 20 bill. If some exec inside Google suggested building a team to "squash docusign" they'd be... silly.. and recognized as such.
Not sure I understand this. Google, for example, routinely does acquisitions well under a $20B level to enter a new market. Apigee might be a good example.
Perhaps you meant too small to occupy the entire new "Blockchain Unit"? Perhaps, but I assume they would be working on several things rather than just one.
Sure, but the goal of the acquisition is to help/kickstart something worth significantly more than that. Apigee was rolled into google cloud - that's a space worth trillions.
Docusign has a big share of the e-signature market. The market itself just isn't very big (by google standards).
