I came here because of the clickbait title, ready to lambast thunderbird for the empty promises... But it turns out that they're pretty clear on the specifics of what separates them from Thunderbird.

But I'm not gonna let that righteous indignation go to waste, so instead I'm gonma rip Sourav Rudra('s writing skill) a new one. Prepare your (writing skill's) ass for a kicking Sourav.

Betterbird: A Thunderbird Fork That Promises Better Features

Better features?! Can I also have updated elements and improved aspects? Maybe superior components too??? Ah. A girl can dream.

Vague buzzwords and nothing more. "Better features" is not only subjective, but also vague enough to be almost entirely meaningless. Let's hope the rest of the article does better.

Thankfully, the author included a shortlist of "Must-Know Bits." I'm sure that's a good summary of what's to follow.

— Features many long-requested features.

I'm glad they're finally listening to my request of compatibility with the Lovense remote control vibrator app's API. Now I can feel good about receiving emails instead of stressed! They sure took their sweet time, it's been long [time units] since I requested it!

How long and who requested? Or better yet, what features????? Why should I care???????? Please, give me somethinbg concrete to grip onto!

— A more streamlined alternative to Thunderbird.

Streamlined! Wow! Is it also more efficient, and higher quality? Will they make it sustainable? Maybe it can also be more ethically sourved.

Could you be more vague please? This almost accidentally told me something about the changes they've made.

— Highly customizable, thanks to Add-ons and Themes.

Like Thunderbird? Like the addons you can find at the official Thunderbird site at addons.thunderbird.net?

Do they also plan to send and receive email in betterbird? Will it work with a graphical desktop environment? Will it be computer software? Or does the failure to mention these assumed "features" imply that it will diverge from Thunderbird in these key aspects?

Deeply shit lead-in. The rest of the article stands in stark contrast, being actually specific and informative. It's like ol Sourav wrote an actually good article, then some idiot editor slapped it in ChatGPT and told it to fart out a title, subtitle, and highlights list. And then ChatGPT ignored all that and made the most generic tech article heading of all time.

FWIW, itsfoss.com: you should fire that editor for being a completely incompetent moron.
