You no longer receive messages sent to Office 365 'Groups' that you are a member of

Ravin Sachdeva- From our point of view, we think the most optimal solution is to have a global default setting that the sender of the message to the group receives a copy of the sent message -- mirroring DL behavior -- as a tenant setting (in case some tenant admins want to toggle the default off for their tenant) and additionally allow each O365 Group member to decide for themselves whether they want to opt out of receiving their own sent messages on the same screen where they opt in or out following the group.  Perhaps there could also be a tenant setting to not allow individual users to override the tenant default. Smaller tenants might prefer to have a single setting for all users. I support a larger tenant with ~100,000 users and we prefer the flexibility to let each user configure their tools and environment as much as possible to whatever the individual feels increases their productivity. When it comes to productivity apps, there is no "one size fits all."

With O365 Groups being marketed as an upgrade of Distribution Lists, every single customer I work with is confused by the current behavior of not receiving a copy and raises a support ticket with our service desk about mail delivery issues and their groups not working properly. This consumes a ton of resources that waste everyone's time and causes additional frustration when people figure out in the end that they're seeing expected behavior. On the other hand, we hardly ever receive complaints about someone receiving too much mail. People just create Inbox rules in Outlook to deal with that or just delete unwanted messages. They don't call the service desk for support.

Could you provide a link to the roadmap item for this? I'm unable to find 76175, which was mentioned by Juan Carlos González Martín, and filtering the roadmap for updates of Office 365 Groups shows only 3 updates, none of which have anything to do with this topic. Even searching for "Office 365 Groups" doesn't show this, although it did find several other changes that weren't tagged as "Office 365 Group" items (It would be good if they were! Since O365 Groups exist as a filter, it never occurred to me before to search and I missed some of those changes in the past.)

Also, just want to add that we really appreciate the effort by Microsoft in response to feedback from customers like us to improve features of the products!
