In my opinion, 56 upvotes is not “lots of feedback”, while they ignore feedback with hundreds if not over a thousand upvotes. They’re ridiculous.

I made a support ticket with Microsoft because they snuck this change in without any notification to Teams Admins. I was told about this change before it was announced and additionally was told they tried to make a toggle to have the metadata stay, but it caused too many issues than good.

In my opinion, Microsoft is getting lazy. No heads up notice to admins. Developers declaring it’s too hard to add an option. I expect much more from Microsoft.

Well, it’s true that people who are pleased with an implementation seldom voice an opinion. However, the folks who were not happy complained at length to Microsoft in the feedback forum, Reddit, Microsoft forums, and so on. I hated the implementation myself and heard many other MVPs voice a concern that a problem existed. So Microsoft changed. Maybe you should register a feedback forum request to add a setting to control whether metadata is included when pasting.

The problem with the chorus of voices saying they didn’t like it is that it could well have just been a noisy minority. All that was ever visible until now was one side of the argument.
Why would anyone who was OK with the old behaviour even think to seek out those conversations to argue in favour of the (now former) status quo?

The metadata included in pasted text was the noise. People just didn’t like it and Microsoft received lots of feedback that including the metadata was unpopular. So they removed it.

Above I read something like “The who/when data was adding more noise than value to user workflow” – I totally disagree.
Where is the noise???

An option might have been a safer way to deploy the change, but it seems like from the comments and user requests that people just didn’t like the metadata…

Any change to existing behaviour should always be implemented as an option.

I disagree that the new behaviour should always have been this way. I would argue that it should be message-only if copying a single message, or even messages from a single user… but when copying a conversation there is no longer any indication of who said what, which means it’s no longer possible to copy/paste into case notes.
The problem with a noisy request like MC878422 is that there’s no easy way to argue in favour of the status quo. Making it an option would have allowed telemetry to give a real picture.
