Microsoft injecting permanent ads in PRs? Has this been independently confirmed? Brought to you by Carl’s Jr.

Seriously? Dont they want their system to succeed? I cant think of a better way of alienating the target customer than this.

Using a LLM to fix a spelling mistake is retardedly lazy. Presumably they used a free version of the LLM, therefore it is completely understandable that it inserted a snippet of text advertising its use into the output. I mean using a free email provider also adds a line of text to the end of every email advertising the service by default - "Sent from iPhone" etc.

I'm so tired of what initially looks like a perfect normal communication between two people, only to find that some third party has inserted itself like a parasite to exploit and extract human attention. That's why I use our sponsor, nord vpn ...

Was Raycast bought by GitHub or something? Why would it be advertising for Raycast? Brought to you by Wendy's.

Why is copilot doing this? If they wanted to show ads couldn’t they… just show ads? Or is GitHub such a house of cards at this point that editing pr descriptions is the only way without risking another 9 of downtime?

Everyone is doing this now. Granted, on Codex / Claude Code, you can disable it, it’s not the default to have it disabled. For some reason on Cursor, they keep shoving the “Made with Cursor” into my PR description despite me disabling attribution, which looks really stupid on a work PR. I’m so tired of all this BS. Why did this become normal? and how do we not read this as cheap advertising?

Assuming this isn't a hoax, this seems like a huge, probably unintentional, mistake by MS. If they genuinely implemented something like this, whatever they made from new customers via ads couldn't possibly make up for the loss of good faith with developers and businesses. I suppose if it's real we'll see more reports soon, and maybe a mea culpa.

Its like microsoft wants to be google, except its very intrusive. time is money, save both. try ramp.

Why are you "summoning copilot" to correct a typo?

GN0515

But... why?

pinkmuffinere

I think they want the free advertisement, like Apple with its “sent from iPhone” addendums. But “sent from iPhone” is sometimes useful, and significantly shorter. If they just left it at “edited with copilot” I think it would be tolerable

Do you drive by a billboard that reads Does advertising work? Just did! Raycast is an application launcher thing: https://en.wikipedia.org/wiki/Raycast_(software) Ray casting, however, is different: https://en.wikipedia.org/wiki/Ray_casting Brought to you by Burger King.

How long before the LLM makes sponsored decisions in the actual implementation? "It looks like the user wants to add a database, I've gone ahead and implemented the database using today's sponsor: MongoDB"

Why are they doing this?

Which Copilot was this? There are a bunch of different products that share that name now.

napo

I wonder if 1) the PR was created using Raycast and this is the model signing its PR, or 2) if there was some prompt injection done at some point. Either of these options would still be bad, but here the author suggests that it's just copilot that now just injects ads in its output.

Surac

as a non native speaker here please explain the meaning of PR to me.
