Martin, I would appreciate that you do not censor this post, as it’s informative writing.
Onur, there is a misleading statement “[…] GIFs are animated images …”. No, obviously you don’t seem to have take much notice of what you were told back in March regarding; Graphics Interchange Format (GIF).
For example, https://www.ghacks.net/2023/03/31/whats-gif-explanation-and-how-to-use-it/#comment-4562919 (if you had read my replies within that thread, you might have learnt something useful). I even mentioned, “GIF intrinsically supports animated images (GIF89a)”.
You linked to said article, [Related: …] within this article, but have somehow failed to take onboard what support you were given by several more knowledgeable people.
If you used AI to help write this article, it has failed miserably.
AI is stupid, and it will not get any better if we really know how this all works. Prove me wrong.. https://www.youtube.com/watch?v=4IYl1sTIOHI
Martin, [#comment-4569908] is only meant to be in: [https://www.ghacks.net/2023/07/09/how-to-send-gifs-on-iphone-two-different-ways/]. Whereas it appears duplicated in several recent random low-quality non relevant articles.
Obviously it [#comment-4569908] was posted: 9 July 2023. Long before this thread even existed… your database is falling over. Those comments are supposed to have unique ID values. It shouldn’t be possible to duplicate the post ID, if the database had referential integrity.
Don’t tell me!
Ghacks wants the state to step in for STATE-MANDATED associations to save jobs!!!
Bring in the dictatorship!!!
And screw Rreedom of Association – too radical for Ghacks maybe
GateKeeper ?
That’s called “appointing” businesses to do the state’s dirty work!!!!!
But the article says itself that those appointed were not happy – implying they had not choice!!!!!!

The current ghacks.net is owned by “Softonic International S.A.” (sold by Martin in October 2019), and due to the fate of M&A, ghacks.net has changed in quality.

Many Authors of bloggers and advertisers certified by Softonic have joined the site, and the site is full of articles aimed at advertising and clickbait.

As it stands, except for articles by Martin Brinkmann, Mike Turcotte, and Ashwin, they are low quality, unhelpful, and even vicious. It is better not to read those articles.

By the way, if you use an RSS reader, you can track exactly where your comments are (I’m an iPad user, so I use “Feedly Classic”, but for Windows I prefer the desktop app “RSS Guard”).
RSS Guard: Feed reader which supports RSS/ATOM/JSON and many web-based feed services.

We all live in digital surveillance glass houses under scrutiny of evil people because of people like Musk. It’s only fair that he takes his turn.
“Operating systems will be required to let the user choose the browser, virtual assistant and search engine of their choice. Microsoft cannot force users to use Bing or Edge. Apple will have to open up its iOS operating system to allow third-party app stores, aka allow sideloading of apps. Google, on the other hand, will need to provide users with the ability to uninstall preloaded apps (bloatware) from Android devices. Online services will need to allow users to unsubscribe from their platform easily. Gatekeepers need to provide interoperability with third-parties that offer similar services.”
Wonderful ! Let’s hope they’ll comply with that law more than they are doing with the GDPR.
No, they didn’t lmao.
