Infosys Buyback - Promoters participation

I am wondering as to why promoters / large investors non-participation in Infosys buyback is acclaimed as too positive… duh… I think its common sense for promoters to not-participate in their buyback offers owing to harsh-taxation (for large investors) on buyback…

Am I missing something… opposing views welcome…

The management believes the stock is worth more than the buyback price. Hence, investors see it as a bullish signal.

Promoter non-participation = confidence + long-term belief + alignment with shareholders’ interests. That’s why it’s acclaimed as positive.
