Even then, some of the reasons are the same. I could get Eclipse from the official site, and even get a newer version that way, but it is still more convenient for me to get it (and almost everything else) from Fedora (or whichever Linux distribution I am using that day), and it would still be the case even without package management.
The comment below by rgmoore makes the same point I was trying to make, perhaps more eloquently.
For Windows, there is the added benefit that these large download aggregator sites are supposed to scan for malware, so it should be safer for nontechnical users than looking for the original site (yes, I am aware of the irony here). This same rationale applies to downloading Firefox extensions only from Mozilla's addons site, even when they are available elsewhere.
