Like most things, it’s about balance. All changes to open source software must be approved by the community managing it, and if that community is lazy or poorly managed or simply too busy then there’s an opportunity for new vulnerabilities to be created, either accidentally or maliciously.

But for well managed software, as other people have said you can get more changes more frequently, more security as many people are evaluating the code base, and greater attention to what users want rather than what’s profitable. Whereas with closed source software there is a greater focus on profitability, and sometimes that leaves vulnerabilities open when development is rushed and/or vulnerabilities are not seen as important enough to justify the cost to fix, but sometimes that tendancy towards profitability can also ensure the product stays a market leader. Steam may be a good example of a good closed source product.

Nice, thanks, I didn’t know about this! I assumed the ads were just an unfortunate necessity to maintain the site, but you can definitely tell there’s a bigger difference when you compare the two.

Aside from email already being federated as others have said, there’s a site called PrivacyTools with lots of links for the other things you talked about and lots more.

Gives real “A QA walks in to a bar and order -26 beers” vibe

I think there are two reasons:

1. Tumblr isn’t nearly as popular as it was 8 or 10 years ago
2. Tumblr isn’t, generally speaking, a well known site for the kinds of tech focused people that would be building such applications. Tumblr has a focus more towards sharing images (even to the extent of screenshotting twitter posts rather than linking the post itself), and generally speaking (again) more tech focused people tend to prefer sites with more generic content, such as lemmy/kbin/reddit where you can have images, links, and text discussions.
