Sun had cash in the bank, Oracle bought that, and came out with a couple of $B, so it was a money making exchange for Oracle. People running Sun made their millions, didn't care about the people or technologies, sold for the best deal with the biggest personal executive payouts possible. Oracle basically did the Sun execs a "favor". Oracle never had real plans to leverage Sun technology, they wanted the short term cash and the patents, almost all of Sun tech was shelved on day one. BTW - Sun had one of the first cloud deployments, ahead of Amazon at the time. But it wasn't made by big-O so "not made here, so no good" and shuttered it to start all over many years later. The contactless store checkout that Amazon does at their brick and mortar stores, was on display at Sun in 2001 in the briefing center at the "Facebook" campus. The destiny of SPARC and Sun software was set by the bad executive management years before the acquisition, and it never recovered because no one had the incentive to do so. Great technology gone, replaced by commodity parts and devops where continuous breakage is okay as long as it is fixed in the next sprint. Sun was completely dead the day it was acquired, most just didn't realize it then.
