• Hacker News1Synology reverses policy banning third-party HDDsSynology reversed its unpopular policy that forced users to buy only Synology-branded hard drives after NAS sales plummeted in 2025. The company faced heavy criticism and customer backlash for the restriction, which made third-party drives from Seagate and WD unusable in newer models.Internal morale and employee impact:Technical and support staff likely fought against the policy internally but were overruled, damaging morale and potentially causing valuable employees to leave. The reversal may be too late to restore trust among workers who felt ignored despite dedicating years to the company.Hardware limitations and lack of innovation:Synology has stagnated with decade-old hardware, outdated Linux kernels, and removed features like transcoding. Competitors like UGREEN and Ubiquiti offer better specs at lower prices, making the drive restriction just the final push for many to switch platforms.Incomplete reversal and trust issues:The policy reversal only applies to 2.5" SATA SSDs and some Plus series models - 3.5" HDDs remain restricted. Many users view this as "too little, too late" and have permanently switched to alternatives, questioning Synology's long-term trustworthiness.
• Reddit science1Using scented products indoors changes the chemistry of the air, producing as much air pollution as car exhaust does outside, according to a new study. Researchers say that breathing in these nanosized particles could have serious health implications.Using scented products indoors, such as flame-free candles and wax melts, can create significant indoor air pollution comparable to car exhaust. Research by Purdue University found these products release nanosized particles that can penetrate deep into lungs and potentially enter the bloodstream, posing serious respiratory health risks.Misleading title scope:Discussion about how study only focused on wax melts but title suggests all scented products, with debate about whether findings could logically extend to other scented itemsHealth concerns from chemist:A chemist's perspective against using scented products leads to sharing of personal health impact stories, from COPD to cancer cases, and debate about necessity of artificial scentsAir purification solutions:Discussion of HEPA filters and other air purification methods as solutions, with debate about effectiveness against different types of pollutants like VOCs and nanoparticles
