Nah, opposition research is only the tip of the iceberg. They were using those fancy govt. issue cyber espionage (weapons) tools for a whole lot more than just eavesdropping on bad Orange Man, and meanie-head republicans.

Stop and consider what a gang of conspiratorial thugs with that kind of power would be capable of stealing- besides elections. ... How about stock market manipulation, and insider trading! The lure of that much money is simply too powerful for those miscreants to resist. "It's rigged, folks."
