Several point out the irony of a privacy-focused organization using broad language around data collection, especially concerning "legitimate interests" and unspecified "service providers." The lack of clarity regarding what data is collected and how it's used is a recurring concern. Some users question the necessity of these changes and express disappointment with Mozilla seemingly following the trend of other tech companies towards less transparent data practices. A few commenters offer more supportive perspectives, suggesting the changes might be necessary for legal compliance or to improve personalized services, but these views are in the minority. Several users also call for more specific examples of what constitutes "legitimate interests" and more details on the involved "service providers."
The Hacker News post "Introducing a terms of use and updated privacy notice for Firefox," linking to a Mozilla blog post, generated a moderate number of comments, mostly focusing on skepticism and mild criticism of the changes. There wasn't overwhelming engagement, but several commenters expressed concerns and observations worth noting.
A significant thread discussed the seemingly redundant nature of having both a Privacy Notice and Terms of Use, with some arguing that the core principles of privacy should be enshrined within the Terms of Use themselves rather than separated into a distinct document. Users questioned the practical implications of this separation and whether it diluted the commitment to privacy.
Some commenters expressed frustration with the length and complexity of legal documents like these, suggesting that they are rarely read thoroughly by average users and serve primarily to protect the company rather than inform the user. The perceived opacity of such documents was a recurring theme.
Specific points of contention arose regarding the language used in the documents. For example, the inclusion of clauses related to account suspension and content removal raised concerns about potential censorship and the arbitrary application of these rules. Commenters also debated the implications for browser extensions and add-ons, questioning whether the new terms might limit functionality or impose restrictions on developers.
A few users questioned the timing of these changes, speculating about possible external pressures or internal shifts within Mozilla that might have prompted the update. However, these comments remained speculative and lacked concrete evidence.
Several commenters pointed out the lack of significant changes in the actual substance of the policies, suggesting that the update was primarily a restructuring and clarification rather than a substantial shift in Mozilla's approach to privacy or user data. This observation led to further discussion on the value and purpose of such updates.
Finally, some users expressed a general distrust of all companies regarding data privacy, regardless of their stated policies. This sentiment reflected a broader skepticism about the efficacy of online privacy protections in the current digital landscape.
