What privacy concerns are raised by Blake Lively's subpoenas in her legal battle with Justin Baldoni?

Blake Lively's legal team has issued extensive subpoenas seeking complete call and text histories, real-time location information, and web browsing data over several years from multiple targets. These requests are considered wildly disproportionate to the case's needs and potentially violate multiple legal protections including attorney-client privilege, spousal privilege, and physician-patient privilege. The subpoenas have been criticized for unnecessarily invading the privacy of numerous third parties including family members, friends, business partners, and essentially anyone who communicated with the targets. This extensive reach appears to go beyond legitimate discovery purposes, potentially abusing the civil litigation process while compromising the privacy of individuals not directly involved in the legal dispute.
