This is in no way standard practice for proprietary software, WTF is with you dystopian weirdos trying to gaslight people? Adobe's suite incl. Photoshop does not do this, Microsoft Office incl. Excel does not do this, professional video editing software does not do this, professional music production software does not do this, game engines do not do this. That short list probably covers 80-90% of professional software usage alone. People do this when serving two versions of a website, but doing this on software that runs on my machine is frankly completely unacceptable and in no way normal.
Maybe then, it's just my expectation of what they would be doing. What else is all the telemetry for? As a side note, my impression is that this is less of a photoshop and more of a website situation in that most of the functionality is input and response to/from their servers.
Telemetry is, ideally, collected with the intention of improving software, but that doesn't necessitate doing live A/B tests. A typical example: report hardware specs whenever the software crashes. Use that to identify some model of GPU or driver version that is incompatible with your software and figure out why. Ship a fix in the next update. What you don't do with telemetry is randomly do live experiments on your user's machines and possibly induce more crashing.
Regarding the latter point, the Claude Code software controls what is being injected into your own prompt before it is sent to their servers. That is indeed the only reason the OP could discover it -- if the prompt injection was happening on their servers, it would not be visible to you. To be clear, the prompt injection is fine and part of what makes the software useful; it's natural the company does research into what prompts get desirable output for their users without making users experiment[1]. But that should really not be changing without warning as part of experiments, and I think this does fall closer to a professional tool like Photoshop than a website given how it is marketed and the fact that people are being charged $20~200/mo or more for the privilege of using it. API users especially are paying for every prompt, so being sabotaged by a live experiment is incredibly unethical.
[1] That said, I think it's an extremely bad product. A reasonable product would allow power users to config their own prompt injections, so they have control over it and can tune it for their own circumstances. Having worked for an LLM startup, our software allowed exactly that. But our software was crafted with care by human devs, while by all accounts Claude Code is vibe coded slop.
I have no idea what you're talking about or why you think I got any information from asking Claude anything. The telemetry comment was about software in general, Photoshop etc., since the person I was replying to was asking what telemetry could be for if not A/B tests. That things are injected into your prompt before sending it to their servers is trivially verified by inspecting your own outgoing packets.
