Agreed; I beleive this is why they have a post for a marketing director/manager to help them with this.
As @jimh54 i believe said engineers often don't report until they "feel" that there is positive progress to report. Which is contrary to what investors want; sure investors prefer glowing reports. However a report is often enough even it is to say they are still working on items & have not been able to mark an item as complete.
Several folks in the forum did ask about the March date for testing; however they answered 2 ppl via email with that being said they should have asked them to keep it under wraps as they are preparing a report to release officially to the community. This would have been received better instead of hearing it through a 3rd party.
The same with folks being enthusiastic about helping with testing. No reason to keep it hushed or vague as it is clear they have already made the selections but who knows what criteria was used.
Hopefully they use this as a learning experience & start to understand in this case critical marketing of this nature requires the communication asked. Simply be honest an answer the questions asked in a biweekly to monthly report. Its simple create a basic report & repost it with changes where needed; followed by Q&A to address questions not covered in the report.
Ie controller/lighthouse progress which has been asked often & returned only by silence.
