In practice, very short texts don't carry very high value so watermarking is (usually) less important. For longer text false positives are not an issue at all since you have a large amount of data to extract your signal from.
I wonder where you got that impression. Several professional watermarking systems for movie studio type content I have worked with (and on) are highly resistant to noise removal while remaining imperceptible.
The wording in the current draft seems to indicate that it applies to "providers of hosting services and providers of publicly available interpersonal communications services". So unless this includes ISPs, I wonder if that means a decentralized P2P service is not covered.
Same here with 20+ years old mail service on the same domain that has never sent spam with correctly configured DNS SPF DKIM DMARC, getting gmail rejections. I noticed a significant improvement after linking the domain to my google account https://support.google.com/mail/answer/9981691
The conclusion of the article says "[...] so far linking (even statically) is done for interoperability, does not [...]". IANAL but it could mean that linking against a GPL library for interoperability is OK in EU, but it does not mean it's true for general case of linking with GPL libraries.
"Much better screen" is also not necessarily true for everybody. For example I can't stand the glossy reflective screen, from what I saw last time I stopped in an apple store it was pretty much a mirror. I find the mate screens on thinkpads vastly superior and less difficult on my eyes, and their trackpads are fine: the magic track pad on my mac mini m1 is fine too, but I don't prefer one over the other.
Often things can be ported easily without much effort, but the issue lies in validation and testing, there are often corner cases that need to be identified and tested, it can cost a lot of time and effort and it's not always feasible. Redhat knows it may be cheaper to purchase RHEL subscriptions in that case.
Displaying the result of a command as a graph (histograms, plots) can be more pleasant than a bunch of **** bars. An external graphic window works well too, but displaying in place can be convenient sometimes, no need to click or alt-tab.
Internet Archive is likely the only memory of the digital world. They may or may not have made a mistake during the covid pandemic by extending their book lending program, but in the age of IA where many text and images are going to lack any source of truth, they may be one of the very few ways to document modern history.
