===Cyberbullying accusations against Louis Rossmann===

On the 1st of August 2024, DCS filed a complaint to the Australian government against Louis Rossmann claiming that they are the target of an "orchestrated cyberbullying attack" by Rossmann and his follower base, with the goal being "to discredit the quality of our products," leading to "millions of dollars" of damage to the company, and demanded that Rossmann be "held accountable" for his actions. DCS claimed that Rossmann's accusations against them are "based on one person's opinion," and involved misinformation and disinformation, which is incorrect, because the accusations are backed up by evidence from various sources. For example, the claim about the rapid deterioration of battery capacity is based on research conducted by ITP Renewables; the report of this research is available on the Australian Renewable Energy Agency's website.<ref>{{Cite web |date=7 June 2022 |title=Public Report 12 (Final Report) Lithium-ion Battery Testing |url=https://arena.gov.au/assets/2018/05/lithium-ion-battery-testing-public-report-12.pdf |website=Australian Renewable Energy Agency}}</ref> Rossmann's claim about warranty fraud is supported by an archived page from their own website, which proves that they falsified their warranty information.<ref name=":0" /><ref name=":1" /><ref>{{Cite web |last=Rossman |first=Louis |date=15 March 2025 |title=DCS reports me to Australian government for cyberbullying |url=https://www.youtube.com/watch?v=DxfNbxmT3B4 |website=YouTube}}</ref>
