I'm so sorry about this. In my view most of the flags were raised rightfully. I had a look at a few of them before any were declined and I was really grateful for the flags on these old posts as we don't often get a chance to clean them up. As you mentioned, some of the links don't even work.
One of the points mentioned in the decline message was that sometimes a link is the only answer, and that was the case for some of the posts. For example, I looked at the flag on this post and I didn't decide what to do, so I did nothing, but I should have marked the flag as helpful and left the post and noted on the flag that I don't want to delete that post because its timestamp indicates that it precedes the better post that contains the same information and more (a corner case of site etiquette). Anyway, sometimes a link is really the answer and shouldn't be flagged as a link only answer. Broken links can sometimes be fixed using Wayback Machine.
But some of the posts were the kind of link only answers that do need to be fixed or removed.
The decline message also suggests that link only answers should be fixed by those who encounter them. I've fixed a lot of link only answers in my time, transcribing videos, quote formatting and paraphrasing material from sources, etc, and it's enormously time consuming. In good times, I would hang out in the Downboat, where many enthusiastic janitorially inclined folks might be hanging out willing to do that kind of wonderful work, but these days, sorry Mum, sorry Jeff, more often than not I just convert potentially useful links into comments :/ Some are not useful and deleting them outright is the right way to go.
I guess my short answer to your question is that I didn't have enough time to finish handling your lovely flags, because I have a 2 year old (who's broken my laptop) and a crochet addiction.
Some of the posts you flagged still need attention (sorry again).

I can't open the URL in this answer - can anyone find that information? <-- link dead and Ubuntu One also gone.
- This answer could be expanded with quotes from the source page.
- This answer has been fixed by BeastOfCaerbannog :)
Without a decent sized screen and keyboard and with an increasingly pressing need to read The Tiger Who Came to Tea yet again, I can't get the above done at the moment, hope someone else can.
I will try to figure out if I can get you unbanned from flagging...
In the meantime, if you are interested, you can post link only answers in the Downboat where people may be able to help fix them.
